I'd say causality and entropy are contingent on the (very compelling) assumption that time is real. We could be Boltzmann Brains, or something even weirder. Do I believe that the world is terribly different from what it appears to be? No, but ultimately our perceptions of the world are merely representation held in our minds.
Or worse.
Presumably the probability of a brain appearing as a disordered psychiatric monster is far higher than the probability of arriving as an Earth-normal tenured cosmologist.
