So as I was writing the entire scope of human history has demonstrated a fundamental truth. For some people this fundamental reality is offensive because it violates their belief system in the same way a radical religious fanatic is offended by other fundamental truths of reality.
That fundamental truth goes something like this. Any individual persons standard of living is dependent on infrastructure. If all you have is your ability to walk while carrying a burden like the Aboriginals SeaGypsy used in his example then your rate of trade is very low. You can build a nation from that foundation, but the assembly takes many generations to form because the infrastructure is virtually non-existent. From this natural abundance of 'sticks and stones' humans learned how to work natural materials into tools and improve on their situation.
Chimpanzee, Bonobo, Gorilla and Orang-U-Tan have been observed in their natural environment picking up natural materials and using them as tools. However so far as we have determined they do not modify these natural materials by very much from their found condition, and they discard them as soon as the particular task they are using them for is complete. For example they sometimes use grass or straw stems to extract ants or termites from mounds to eat. They will use sticks and rocks as clubs or hammers to break open nut shells to extract the edible portions inside, or to display their abilities to attract mates. For these 'cousins' of ours the step from tool use to tool manufacturing has not taken place.
For us the better our tools the more speed and efficiency we have used to improve our infrastructure, which in turn has given us greater standards of living. The pinnacle of this process before fossil fuel use were animal towed canal boats. When we started out as stone age humans on foot we could reasonably carry about 30 kg of material for trade about 15 km per day. When we got to pack mules we could haul about 100 kg per animal in a caravan.
When we got to travois we used simple leverage to drag twice as much per human/animal.
http://www.backcountrychronicles.com/travois-game-drag/A travois is just about the simplest device you can use to give you a mechanical advantage when moving any burden from place to place.
The next step up from a travois is the wheel. By putting a wheel between the burden end of the travois poles and you reduce the force needed to pull your burden so long as you are on relatively flat and firm terrain. On moderate hills a travois offers advantages because it resists the pull of gravity better when going up hill and doesn't easily roll forward going down hill.
A travois based cart on a flat firm surface increases your burden capacity by another factor of two, depending on the length of the draw bars and the slope of the terrain. The biggest disadvantage is that the wheeled version of cart or wagon requires more than a game trail quality pathway. With a narrow cart with a single wheel, like a Wheel Barrow, you can traverse relatively rough terrain but there is a much greater risk of tipping over and having to re assemble the burden into a compact mobile configuration. The first roads were intended to improve this by widening and leveling the pathway by hand. Game trails in general are no more than two feet wide when passing through woodlot in my experience so humans pulling burdens had to create their own 'roadway' around obstacles. During the stone age these roads were little more than paths that bypassed natural features like marshes or dense stands of trees to provide routes during the dry season or in the colder regions the frozen season. During the wet season you only went as far as absolutely necessary because mud is exhausting to travel through.
When native copper and tin and lead were discovered and formed into tools of bronze or pewter infrastructure improved again, this time by using those metal tools to more effectively widen and flatten roads, and in resource rich places to even pave them to a certain extent. I grew up not far from a road called 'the old Plank road' that was first improved by laying logs crossways through a semi swampy area bordering the local river. The logs were not bound hard up against one another when the road was constructed. They were more like railroad ties that would prevent wheeled vehicles from sinking up to the axles in mud during the spring and fall wet seasons. It must have been a jarring experience for people in the 1800's to use it, but it worked, and all it required was a stand of trees and much labor with axes and saws. The next improvement was when they nailed planks across the embedded logs to give the oxen and horses firmer footing and the passengers a smoother ride.
When iron tools came along in the 1100 BC period of ancient Greece in Europe and around 700 BC in China stone working took on an entirely new context. Instead of seeking out frangible stone to be shaped into tools humans now turned to stone as a workable building material. Some stone work was done long before iron came along, the ancient Egyptians used bronze and even hammer stones to build the first pyramids and obelisks. Even the Inca, Maya and Aztecs of the America's built many worked stone structures without metal tools. However when the Iron tool arrived the ease of building was much greater. When the Roman Empire arose they took stone work construction to new heights with thousands of miles of roads, thousands of bridges, aqueducts for water, stone buildings and paved streets in cities. Each of these infrastructure improvements lead to more robust trade in all seasons. A hard surfaced properly drained road is usable in the rainy season or drought, unlike the muddy roads they replaced. Even the first practice of excavating drainage ditches along side otherwise dirt roads caused them to dry out much quicker after the rainy season ended.
All of these advances from foot to travois, to cart, to wagon were accomplished with hand labor and renewable fuels. Boats on lakes and rivers and ships upon the sea were also built from mostly renewable resources and required no fossil fuels. Galleys were the most common designs where human muscle provided the energy to move with supplementary sails to help when the wind was blowing the right direction. Galleys remained competitive transportation for several thousand years, only being fully displaced in the late 1700's in Europe when sailing ship technology finally surpassed them. Each and every one of these transportation improvements played its part in raising the general standard of living of the average human in the effected area.
Finally the pinnacle arrived. Well actually not finally because canals were being built as far back as the Bronze age in Egypt. I don't mean the irrigation canals either, I mean the boat canals that first served galleys, and then eventually cargo boats towed by animal power. At their peak around 1840 in Europe and North America and China a simple canal boat with one person handling the tiller and a second guiding the draft animal could move the weight of the boat plus sixty metric tons of cargo. The transition from 30 kg carried by a human to 60,000 kg carried by a canal boat took about 70,000 years. But nothing in that entire time required any use of fossil fuels to accomplish. If you lived anywhere on a river or canal network served by tow boats your standard of living was greater than that of any king or queen who reigned before 1500 AD. You had a much greater selection of foodstuffs to choose from at a lower price, and because of the low transportation costs provided by the infrastructure you could afford to import goods from incredible distances. Where common people before 1700 AD rarely traveled further than 30 km from the spot where they were born over a 70 year lifespan you could book passage on a canal boat and cross England or France or Germany within a week. In 1840 you could start out in Albany, New York and be in Toledo, Ohio in ten days, a distance of 950 km. All of this, every bit of it, was accomplished without the use of fossil fuels in any meaningful quantity.
