Here is a situation where you make an “observation” and can still interact with the other possible worlds. Maybe you do not want to call this an observation, but if you don’t call it an observation, then true observations probably never really happen in practice.
I was not trying to say that is relevant to the coin flip directly. I was trying to say that the move used to justify the coin flip is the same move that is rejected in other contexts, and so we should open to the idea of agents that refuse to make that move, and thus might not have utility.

Ah, that’s the crucial bit I was missing! Thanks for spelling it out.
