Let's ditch the gnomes, they are contributing little to this argument.

My average ut=selfish argument was based on the fact that if you changed the utility of everyone who existed from one system to the other, then people's utilities would be the same, given that they existed.

The argument here is that if you changed the utility of everyone from one system to the other, then this would affect their counterfactual utility in the worlds where they don't exist.

That seems... interesting. I'll reflect further.

Yep, I think that's a good summary. UDT-like reasoning depends on the utility values of counterfactual worlds, not just real ones.

I'm starting to think this is another version of the problem of personal identity... But I want to be thorough before posting anything more.
