This whole setup presupposes something like a Standard Model spacetime as the ‘seed substrate’ upon which Boltzmann brains or Boltzmann simulations are generated.
It completely neglects the possibility that our entire universe, and all its rules, are themselves the result of a Boltzmann simulation spawned in some simpler and more inherently fecund chaos.
Ah yes, but if you start assuming that the standard model is wrong and start reasoning from the “what kind of reality might be simulating us”, the whole issue gets much, much more complicated. And your priors tend to do all the work in that case.
One serious problem I see:
