Yes, amount of utopiastuff across all worlds remains constant, or possibly even decreases! But I don’t think amount-of-utopiastuff is the thing I want to maximize. I’d love to live in a universe that’s 10% utopia and 90% paperclips! I much prefer that to a 90% chance of extinction and a 10% chance of full-utopia. It’s like insurance. Expected money goes down, but expected utility goes up.
Decision theory does not imply that we get to have nice things, but (I think) it does imply that we get to hedge our insane all-or-nothing gambles for nice things, and redistribute the nice things across more worlds.
