We tried to be clear that we were discussing influenceable value, i.e. value relevant for decisions. Unreachable parts of our universe, which are uninfluenceable, may not be finite, but not in a way that changes any decision we would make. I agree that they are part of the universe, but I think that if we assume standard theories of physics, i.e. without child universes and without assuming simulation, the questions in infinite ethics don’t make them relevant. But we should probably qualify these points more clearly in the paper.

As I said, the story was in combination with one-boxing decision theories and our duplicate counterparts.
