This, in a nutshell, is why altruism exists in humans. It’s limited and partial, but it solves the problem of cooperation by breaking the condition that everybody is solely looking after themselves.
Also, this is where acausal decision theories do very well at cooperation. Pretty much all the negative results on cooperation implicitly assume causal decision theory is being used.
Indeed, for acausal decision theories, identical copies cooperating is the case where it’s easy to prove that they cooperate, which explains why the body has identical cells (And why the body suppresses foreign things so harshly).
