Exactly! Â You have a hypothesis that is physically impossible to test. Â So it is junk science to think that the experiments are testing the hypothesis. Â They aren't. Â They are only confirming that the predictions of QM are correct. Â Which is good.
Under the hypothesis of local realism, Bell's inequality follows; and it is possible to test, up to statistical error and statistical uncertainty, whether or not Bell's inequality holds.
The hypothesis of local realism has observable consequences.
