Duende, so, tell me again, what is going to make you sell Cove A to the developer?
You have evidently never bothered to look at your own life from a third person perspective. I suspect you have a source of income; what do you spend that income on? Does 100% of it go towards earning more income? Fuck no, you spend it on total losses, such as housing, food, entertainment, family, and charity. You put a percentage of it towards earning more in the future, such as education or investments, but the vast majority of your income is spent on non-investments.
It just so happens that society is just like you: the vast majority of money is spent on non-investments that will never return a dime (with some exceptions, children can be considered an investment into their future wage income; a house to live in may sell for more than you paid, etc).
Similarly, it is not the case that protectors are in direct competition with developers: lots of options exist, and we as a species only have use for so many LNG ports. That is why after all these centuries we still have undeveloped coves: developing them all would be a waste of effort.
Similarly, the profits from development flow to society, not development. What the enriched individuals choose to do with their share is up to them. If I owned the developer I may take my share of the profits and preserve Cove C, if for no other reason that to prevent competitors from building their own LNG port
Society is rediculously complex; whether land gets developed or not is similarly complex. Some land is being held in trust to preserve it; some land is being held by people lacking the resources to develop it; and some is being held by corporations just to keep others from getting it; and lots of land has simply been forgotten because no one has use of it. It is this last reason why so much land is still untouched today, apathy.
And this apathy continues. From the developers perspective, other coves exist; so if you preserve this one you have cost them nothing. So, again, why are you throwing away your income on causes (such as entertainment, a big house, etc) when you could be putting it towards preserving natural wealth which, according to Alcassin, is priceless.
Now, I disagree; I don't think the species in question were of any value. They were seamlessly replaced with other heartier species and so I would not waste my money preserving them. But, again, you go right ahead.
