That's then an artifact of invoking an effective collapse of

that only has local interactions, so there is then nothing to
explain in that case. In the latter case, the entangled state
itself results from the local dynamics, one can put ALice and
Bob at far away locations there and wait until the two
particles arrive at their locations. The way the state vectors
of the entire system that now also includes the state vectors
of Alice and Bob themselves evolve, has no nontrivial
non-local effects in them at all.
Sure it does. The state vector itself is a function of spacelike
separate events, which cause it to evolve into orthogonal
components...whose statistics violated Bell's inequality.

There is no non-locality implied here unless you assume that the
dynamics as predicted by QM is the result of a local hidden variables
theory.

There is no need to suggest local (or non-local) hidden variables. The
non-locality we are talking about is implied by the quantum state itself
-- nothing to do with the dynamics.
