But that type of non-locality has never been questioned, neither in the MWI, or a fortiori in QM+collapse. But the MWI explains without the need of “mysterious” influence-at-a-distance, which would be the case in the mono-universe theory, or in Bohm-De Broglie pilot wave theory. Without dynamic we have “only” d’Espagnat type of inseparability.
