I agree with you, I think, but I don’t think your primary argument is relevant to this post? It’s arguing that your “physical” current reality is a simulation run for specific reasons. That is quite possibly highly relevant by your criteria, because it could have very large implications for how you should behave tomorrow. The simulation argument doesn’t mean it’s an atom by atom simulation identical to the world if it were “real” and physical. Just the possible halting criteria might change your behavior if you found it plausible, for instance, and there’s no telling what else you might conclude is likely enough to change your behavior.
