Wow, that was excellent, thanks for writing that.

most any utilitarian would agree that for altruism to be valued it itself must be encoded in the valuer's own utility function, tautologically so. Someone who values personal procreation over "charities" is as moral as the perfect altruist, each fulfilling their respective utility functions

I actually think that many effective altruists/ utilitarians would disagree with that and assert that there is precisely one correct moral action or use of money at any one point in time - it varies based on circumstance of course but for any one circumstance there is one correct action. Rachels would certainly disagree with that, and jeff kaufman seemed to be convinced by Rachel's argument.
