Well said, gonin02 -- that Greenspan essay is one for the Ages, isn't it? Pretty hard to believe he's repudiated those thoughts -- he just has a different day job now.

Let's see if I can recall the five main characteristics of money, off the top, right now:
Durability
Divisibility
Malleability (not sure I'm not just hallucinating this one, before my morning coffee)
Portability
Scarcity
hmmmm... I better look this up --- ok, Wikipedia has something
wiki$this->bbcode_second_pass_quote('', 'M')oney is an agreement, between a community, to use something as a medium of exchange, which acts as an intermediary market good. It can be traded and exchanged for other goods. The agreement can either be explicit or implicit, freely chosen, or coerced. Money is an abstract form of power. As discussed below, money also has other characteristics.
Money itself must be a scarce good. Essential characteristics of money Money has the following three characteristics:
1. It must be a medium of exchange
When an object is in demand primarily for its use in exchange -- for its ability to be used in trade to exchange for other things -- then it has this property.
This characteristic allows money to be a standard of deferred payment, i.e., a tool for the payment of debt.
2. It must be a unit of account
When the value of a good is frequently used to measure or compare the value of other goods or where its value is used to denominate debts then it is functioning as a unit of account.
A debt or an IOU can not serve as a unit of account because its value is specified by comparison to some external reference value, some actual unit of account that may be used for settlement.
For example, if in some culture people are inclined to measure the worth of things with reference to goats then we would regard goats as the dominant unit of account in that culture. For instance we may say that today a horse is worth 10 goats and a good hut is worth 45 goats. We would also say that an IOU denominated in goats would change value at much the same rate as real goats.
3. It must be a store of value
When an object is purchased primarily to store value for future trade then it is being used as a store of value. For example, a sawmill might maintain an inventory of lumber that has market value. Likewise it might keep a cash box that has some currency that holds market value. Both would represent a store of value because through trade they can be reliably converted to other goods at some future date. Most non-perishable goods have this quality.
Many goods or tokens have some of the characteristics outlined above. However no good or token is money unless it can satisfy all three criteria.
I also recommend reading Peter Bernstein's book, although it is frustratingly full of tales of blood and gore associated with gold-seeking and short on modern financial applications.
Geez, I've always wondered about that "10 goats" situation. I mean, if people will haggle over the price of ONE goat, then wouldn't any recipient want to cherry-pick the BEST 10 goats out of the herd? Do we see a problem here?
So, WHICH bottle of alcohol will you specify in your contracts?

Let's say I were to put all of my wealth pre-Peak Oil into diesel generators, which I thought would hold value for me and buy me the things I want later. Well, I am really
speculating on the "price" (in whatever future good) I can get for my diesel generators. And I'm pretty vulnerable to some Chinese company coming along and flooding the market with cheap diesel generators. (Actually, I'd probably do better stocking up on windpower parts, but -- similar risks no matter how noble the business intention.)
I might want to diversify into bottles of whiskey. But -- same problem, eh? And not if everybody else goes into the whiskey-storing biz. "Sorry, Bud. Got enough of my own already."
Gold represents ultimate diversification, as its conversion
back into whiskey, or generators, is likely to be smoother, and with less transaction cost/loss, then, say, trying to turn generators into a drink of whiskey on a Friday night.
Yes, some commodity or asset MIGHT appreciate in price, relative to gold. If you KNOW what that is going to be, then by all means, stock up a boatload. Your profit will more than cover the sales costs back into other goods.
BUT -- you don't know, do you? Nor does everyone else. (Think of tulip bulbs for a moment, please.) That is why money exists -- to cover the general uncertainy about the basket of
all prices, and to allow us to cheaply move from one good to another, as we need or choose to.
