That pre-determined value idea is exactly local hidden variables, and Bell's inequality rules it out, Aspect's 1982 CHSH experiment measured the violation.

To be precise, Bell's inequality rules out a local hidden variable theory. Pilot wave theories/Bohmian mechanics is an attempt to describe a nonlocal hidden variable theory of quantum mechanics.

I've got a feeling that our intuitive ick around spooky action at a distance is due to out intuitive view on locality and the nature of space, maybe time too, being wrong. IOW remote is really not remote.

Perhaps we've got it backwards and quantum entanglement is what defines "locality" rather than mysteriously existing in the face of it.

it doesn't if you assume superdeterminism

If you saw that in section 15, the very next paragraph covers Bell.
