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.
