I think you're suggesting that we think of decisions as selecting which of
the you-like beings is really you, instead of as changing the universe
somehow. This seems like a promising approach, and I've tried it too, but
I haven't figured out how it can be formalized. It may require a
different formal framework from "classical" decison theory.
