Now I’m not understanding how your response applies.
My point was: the entropic principle estimates the probability of observers per unit volume by using the entropy per unit volume. But this follows immediately from the second law and conservation of phase space; it’s necessarily true.
To the extent that it assigns a probability to a class that includes us, it does a poor job, because we make up a tiny fraction of the “observers” (appropriately defined) in the universe.
