Firstly, this kind of multiverse is esentially the same as a parallel worlds one; the only difference is which dimension you take the multiplicity to occur in. I prefer parallel worlds as it implies a logical branching structure, a cladistic tree which provides an overlying system to the otherwise arbitrary worlds.

Second, without some kind of anthropic principle or similar filtering mechanism, then islands of order only appear at the very tip of a mountain, surrounded by masses of increasing disorder. Any order that has been apparent so far has no reason not to disappear in a fizz of entropy in the next moment.

My main feeling on this is that the very makeup of our brains and consciousness requires a universe that works in a certain way. We impose things like time and who knows how may other basic laws onto the world just because they are written into our souls.
