I agree, that’s a more accurate description. The sense in which “true prisoner’s dilemma” is impossible is the sense in which your utility function is the cooperative one you commit to. It makes sense to think in terms of your “personal” (original) utility function and an “acting” utility function, or something like that.
I still think this undermines the point of the “true prisoner’s dilemma”, since thinking of humans gives decent intuitions about this sort of reasoning.
