I’m not sure it matters to the analysis. Whether we have a Tegmark multiverse, or Everett MWI with some decisions depending on quantum randomness and others classically determined, or whether the multiple worlds are purely subjective fictions created to have a model of Bayesianism; regardless of what you think is a possible reduction of “possibly”; it is still the case that you have to live in the reality which you helped to create by way of your past actions.
agreed, it’s not like scientific analysis requires the laws of physics to have no quantum randomness source etc, rather it is satisfied with finding the logical necessities between what is used to describe the observable universe.
That’s not how MWI works, unless human brains have a quantum randomness source that they use to make decisions (which does not appear to be the case).

Now we do.
