But that is not going to explain the Bell correlations which involve measurements at two distinct spacetime points. You are just sidestepping the issue -- show me this magical local state that is non-separable. The fact that you keep ducking and weaving on this question, and similar questions, suggests quite strongly that you do not have an answer -- that you do not have a local account of the correlations, in MWI or in any other theory.
