MW has to show that decoherence is a natural consequence, which is the same thing. It can’t be taken on faith, any more than entropy should be. Proofs of entropy were supplied a long time ago, proofs of decoherence of a suitable kind, are a work in progress.
So once that research is finished, assuming it is successful, you’d agree that many worlds would end up using fewer bits in that case? That seems like a reasonable position to me, then! (I find the partial-trace kinds of arguments that people make pretty convincing already, but it’s reasonable not to.)
The other problem is that MWI is up against various subjective and non-realist interpretations, so it’s not it’s not the case that you can build an ontological model of every interpretation.
