> What happens when I already have all the calorific or reproductive value I need?
How would you even determine how much you need? You labor under the illusion that you're an intelligent being. Evolution does not care about "enough"... because there is no way to determine what "enough" is. What is enough today will not help you survive tomorrow's famine. Best stock up now. If you were so smart, you'd get that. What others call greed is subconscious anticipation of calamity.
Evolution has not solved the principal-agent problem.
> What is enough today will not help you survive tomorrow's famine.
Tomorrow's famine will be caused by you (read: those behaving as you describe) not knowing when enough is enough. Best preserve what we have, rather than waste it all in a frantic bid for number-goes-up.
Maybe it's moralizing, but I don't think it's wrong. I'm using the same model as you, after all, only I'm applying Kantian ethics instead of unconsidered egoism.
• If you wish yourself maximal reproductive fitness, then all humanity will be your descendants, and the next few centuries of all human interest is your interest.
• The iterated prisoner's dilemma is a classic economic argument, by which Tragedy of the Commons-type behaviours can be averted. (Garrett Hardin's 1968 paper is a load of nonsense.)
I'm not sure what would contrast my earlier "leftist moralizing", because I have absolutely no idea what a leftist is.
