> we know now QM is non-local, and that the underlying justification for the Copenhagen model is an extraneous philosophical proposition.
What underlying justification are you talking about and what do you understand by "the Copenhagen model" precisely? At least in the Einstein vs Bohr debates the one denying that QM could be a complete theory because of its non-locality was Einstein, I think.
> Einstein's refusal to accept the revolution as complete reflected his desire to see developed a model for the underlying causes from which these apparent random statistical methods resulted. He did not reject the idea that positions in space-time could never be completely known but did not want to allow the uncertainty principle to necessitate a seemingly random, non-deterministic mechanism by which the laws of physics operated.
The underlying assumption for Copenhagen was to try to preserve locality by assuming non-determinism. However, there’s no saving locality — and non-locality is enough to leave determinism — so there’s no reason for the non-deterministic axiom.
I think I also meant “definite” instead of “deterministic”, but it works out the same.
