That's a good point. Of course if all possible universes eventuate with equal probability, the 2nd law will hold because that is just what is assumed by it - there are a lot more ways to age than to stay young. But why "with equal probability". Bruno's UD must produce some measure on the universes it generates, but it's not clear that this agrees with the physicists equi-probable (hence the white rabbit problem. Incidentally why do we call it "the white rabbit problem"? White rabbits are quite common. Why isn't it "the white crow problem"?)

You imply that our theories are just a matter of "favor". If our theory is one supported by the scientific method (and like the 2nd law maybe very much contrary to our favor) then it is the best tool we have for speculating about things we cannot (yet?) test. There's a difference between wishful speculation and informed extrapolation. They may both be wrong, the latter is the way to bet.
