I think taking a fundamental look at this problem could be fruitful. Here is an idea from an article that I have been working on hopefully to publish. Imagine the MW to be total chaos (like the primeval chaos, Tohu va Bohu, full of potentialities but with nothing inside???) . Time could then be

excluded by the (generalized) anthropic principle, so we explain satisfactorily why we see "C". However, I think that the "everything computable is realized" hypothesis would predict m(A)>>m(B)>>m(C), and so the reason why we are in C is much more mysterious with this hypothesis. Of course if you think you can justify also m(C)>>m(B) with comp, it would have the bonus to explain why physical laws exist (which must be postulated in the first stage), but I am really not convinced of that.
