    Applying the MWI to this situation, it would look something like
    this; you go into a restaurant and have coffee. As a result,
    immediately, another universe is created which has a copy of you,
    inclusive of your memories, where you DON'T to go into the
    restaurant. Can't the see the foolishness of what the MWI
    assumes? Namely, everything that's possible to happen, MUST
    happen. AG *

    Yes, that's a common conclusion and presumably why this is called
    the "everything-list".  It isn't actually an implication of QM
    though.  QM forbids lots of things,
    https://arxiv.org/abs/quant-ph/0702121v1
    <https://arxiv.org/abs/quant-ph/0702121v1>. And MWI is just an
    interpretation.  We don't have a quantum theory of spacetime and
    when we do it may rule out the MWI. So one shouldn't become too
    invested in it or it's contrary.

Yes, MWI is just an interpretation that is meant to make QM palatable to our macroscopic or classical-ish ideas on reality. There is no creation of separate worlds really. The superposition of states exists prior to and after an observation or decoherent event. It is just that with this "EVENT" an observer or decoherent set of information is carried along one superposition in the Hilbert space, while of course there are other such superpositions as well. Somehow, and Dieter Zeh had this idea of "many minds interpreation," we are conscious of one path.

Because each of "we" is numerous.

But it seems you have not heeded my warning about taking MWI too seriously.  You write as though it were well established fact.
