Given

collapse, all the other sectors objectively exist, it's just that

arisen via local dynamics.
Yes, and all that is possible because Many Worlds is local but not
realistic, in comparison to something like Pilot Wave Theory which is
realistic but not local, or Shut Up And Calculate which is, ....
well..., adherence to that viewpoint insist I'm not allowed to say, or
even think about, what it is.

Indeed. Also what Sidney Coleman said here:
