The absurdity heuristic is not a good way to decide what is true. People once thought that the idea of humans being descended from monkeys was absurd. Or that the earth going round the sun, rather than vice versa, was absurd.

Occam's razor is more sensible than the absurdity heuristic, but it applies to the fundamental building blocks of a theory, not to the outputs it predicts. So it would cut against a hypothetical unknown set of "balancing forces of entropy and order", since that's an entity not required by our current best known theories.
