But comp and platonism already predict some non computable physics. You
said it yourself by pointing correctly that platonism leads to the
apparent possibility of HP universe (Harry Potter Universe, or flying
pigs, or random noise, ...). The mystery with "naive comp" is that it
remains something apparently computable in our neighborhood.
And that "mystery" cannot be used as a straightforward refutation of
comp, once we look at the non trivialities of computer science and of
consistent self-referential discourses.
If we bet on comp, then we can already bet we already live in a
simulation, the natural one which emerges from the "creative nature" of
the relations between numbers.
