I question whether there would be a conceptual catch in EPR proposal to get both non commutative variables define with accuracy at one location simultaneously. The idea of separability that EPR introduced to questioning the completeness of QM is that whenever one measures a physical variable q at Alice location, one can predict with absolute accuracy the-q of Bob particle without disturbing it. My claim is that there is still uncertainty in p variable (the other non-commutative variable) of Bob`s particle simply because it is not yet measured. So the prediction of one of non-commutative variable does not mean that both variables are known before the measurement taken place on the other variable. And consequently, this does not grantee that Bob particle possess elements of reality regarding p and q.
