Because in physics experiment is king, and however intuitive naive realism may be something conflicts with it, We know from experimental results that Bell's Inequality is violated, therefore we know for certain that if the universe is deterministic then it can't be both local and realistic, at least one of those 2 things must be false. I don't see how locality could be wrong. If things were non-local a change anywhere would instantly change everything everywhere and the effect would be undiminished by distance, so before you could understand anything you'd have to understand everything. We certainly don't know everything but we do know something and I don't see how we could if things were non-local. And if things are not realistic then the moon doesn't exist when nobody is looking at it, and that seems like too high a price to pay for determinism. Actually if Everett is right then you could have all 3 to the multiverse's point of view because it evolves according to the wave equation and that is completely deterministic, but that's a bit of a cheat because you can't have an observer outside of the multiverse looking in at it. > >*when that assumption is not used in calculating probabilities* > It doesn't matter what your favorite quantum interpretation is or what your philosophical ideas about determinism locality and realism are, we all calculate the same way and get the same probability. Everybody agrees about how the world behaves but disagree about why it behaves that way. However nobody has performed an exparament that can decide which of the various interpretations is correct, and most working physicists aren't very interested in philosophy, and that's why most favor the "shut up and calculate" quantum interpretation.
