Why not adopt ultra-determinism. Since Everettians insist on strictly
determinist evolution it's plausible that Alice and Bob's choices are
determined too...they're not unphysical beings .

Bell’s theorem demonstrates locality and realism cannot be true of a
quantum system. If one performs measurements of observables,
eigenvalues that real, then locality does not apply. Wigner’s friend
argument illustrates how we can show reality may be abandoned. The
following experiment illustrates this. Two observers may witness
nature in ways that are not commensurate with each other. The observer
then cannot be completely removed from nature.

This is a Bell type of experiment where locality is imposed, but two
observers witness two different version of reality. There is then a
loss of objectivity to reality, which is the flip side or dual to the
standard Bell inequality violation used to demonstrate nonlocality.
