A lot of people make statements which assume the truth of some particular interpretation of quantum physics, without realising that it is just one of many. Many advocates of "quantum mysticism" are adopting the von Neumann-Wigner interpretation ("consciousness causes collapse"), and they often misidentify that as "Copenhagen" even though it isn't. But on the other hand, many of their detractors are committing a similar error, and presuming Copenhagen or many worlds as if it was the actual physics as opposed to just one of many competing philosophical interpretations of it.
Assigning metaphysical implications is declared out of bounds. It's a useful compromise.
What you are suggesting is there is a hidden variable theory.
