I don’t think Eliezer (or Everett or Deutsch) thinks “worlds” are ontologically fundamental.
Neither is the wave function collapse, but it is much simpler a concept. The most common objection “how does it do that?” is now irrelevant, since the collapse is not “ontologically fundamental”.
The “worlds” are a phenomenon...
And now you are talking about it like it is some real thing, not an emotional crutch.

How does collapse appear as a non-ontological phenomenon?

Well it was you who brought up “worlds” in the first place! I’m happy to just talk about a wave function on all of Hilbert space evolving through time.
(EDIT: I just noticed I used “Hilbert space” wrongly in this post and the grandparent. I meant to say something like “classical configuration space”. The Hilbert space is the space of complex functions on the configuration space.
I think. QM has so many vector spaces inside each other my brain sometimes melts.)
