being separated in space vs. being separated across different branches of the wavefunction seem pretty similar in terms of specification difficulty
Maybe? I don’t really know how to reason about this.
If that’s true, that still only means that you should be linear for gambles that give different results in different quantum branches. C.f. logical vs. physical risk aversion.
Some objection like that might work more generally, since some logical facts will mean that there are far less humans in the universe-at-large, meaning that you’re at a different point in the risk-returns curve. So when comparing different logical ways the universe could be, you should not always care about the worlds where you can affect more sentient beings. If you have diminishing marginal returns, you need to be thinking about some more complicated function that is about whether you have a comparative advantage at affecting more sentient beings in worlds where there is overall fewer sentient beings (as measured by some measure that can handle infinities). Which matters for stuff like whether you should bet on the universe being large.
