 Of course no such conclusion follows from our freedom of choice. It is not sufficient to be able to choose at will which quantity to measure; for the conclusion to follow from the Criterion alone one would need to be able to measure both quantities at once. This is precisely the point that Einstein recognized in his  1932 letter to Ehrenfest  and that EPR addresses by assuming locality and separability. What is striking about this version is that these principles, central to the original EPR argument and to the dilemma at the heart of Einstein’s versions, are obscured here. Instead this version features the Criterion and those “elements of reality”. Perhaps the difficulties presented by Podolsky’s text contribute to this reading. In any case, in the physics literature this version is commonly taken to represent EPR and usually attributed to Einstein. This reading certainly has a prominent source in terms of which one can understand its popularity among physicists; it is Niels Bohr himself.
