If two worlds within this everything are contradictory or not consistent
with each other, with no common ground, how exactly do they interact? I feel
two such worlds must be independent entities within the set. This is
different from the case of universes which may be linked by wormholes or MWI
splittings or whatever.

I imagine all possible programs for all possible universes. If there were a
single program running the whole show, I would ask, why that program?

As I mentioned in my reply to scerir, we can't avoid self-referential
problems, however, if we try to represent or describe ourselves.

True, there is no necessity in avoiding fine-tuning. It just makes the model
more compelling in my opinion.
