I agree that intuitions are challenging here but I really cannot think of a reason to believe that my actions are less meaningful or that reality is any more or less permanent if we’re all being simulated. So maybe there is a tie there to solipsism as I don’t think I have any problems with simulations that are faithfully executing our physics and not making some sort of patchwork Sim in which I’m the only sentient. If I thought Solipsism was .5 probably then I’d have the problem you describe.
