I never really understood such arguments. Not being combative, just not sure. If we are in a simulation, then why do things like energy matter? Who says those are meaningful in the "real" world. We can only perceive the simulation, so our idea of physics is whatever the simulation creator thought would be nice, no? May be there are things we can infer from this "simulation" about the world one abstraction above, but in nested simulations that would be arbitrary as well.
