No, I am only considering the possibilities. *If* the wave function is
physical, *then* instantaneous collapse implies that something nonlocal
is happening. If it is not physical, then its collapse does not imply
anything nonlocal.

I agree with you that the wave function is not physical. However, I
admit that I could be proved wrong.
