I think you're still missing the point of the UDA. An ensemble like
the all strings ensemble (or UD*) necessarily predicts a predominence
of OMs of high measure that are the consistent continuation of the OM
we experience now.
My argument is that some required property of the observer steps in to
prevent these states from being experienced. Another way of looking at
it is to see that evolution is the only information generating process
in the Multiverse, and the evolution requires heritability, also known
as preservation of information. From this, the axioms of quantum
mechanics follow, which are sufficient (perhaps) to banish the white
rabbit.
Anyway, there is a connection between this heritability requirement
and the robustness requirement I use in my White Rabbit treatment,
although I haven't connected the dots.
