How can you justify logic from physics if logic is primary to prove anything? You're building your lower layer upon an higher layer... It's contradictory.

The truth of them are inconsistent if only real is physically realised computations... Even the notion of realised computation proved by definition that computation is not a physical notion. Existence is not a matter of definition. Rules of inference are abstract, not concrete, but abstractions do not contradict the concrete.
