At the time quantum theory was being developed the majority of philosophers of science also felt that speculations about "reality" were meaningless philosophic navel-gazing. They called these "pseudo-problems".

It wasn't the full-time philsophers who were worrying about whether physics really was describing reality.

The "philosophers" who had these "navel gazing" discussions of which you disapprove were the same scientists that developed the theory, Planck, Einstein, Schrodinger, Bohr and others and these discussion had real implications about the way the theory developed.

And why do you think that this is a point against the philosophy of science? The "navel-gazing" by the major scientists of the 20th century was the process that led to the design of many of those experiments.

But if you do not care whether or not physics is describing "reality" then the Copenhagen Interpretation is fine. As Bohr said, who cares if the Moon is there or not when no-one is observing it, you couldn't possibly test that anyway.

Spooky action at a distance is only "spooky" if you have in intuition that physics is describing "reality" or some version of it that you are expected there to be. Otherwise it is quite uncontroversial.

There is no measurement problem unless you are making the assumption that there really is a Universe.

But physicists like to think that they really are describing reality. Hence the continuing discomfort with the Copenhagen Interpretation.
