I'm not sure I see your point. What exactly do

As you know, I would find the measure distribution
of conscious computations by counting their
implementations. That's all that really matters.
With the UD example, if there is some program in
the UD'd set that acts like a universe simulation, it
will probably give rise to most of those. It will
have "brains" which are the sub-parts giving rise to
such. All of this is just extra definitions for the
sake of convenience.
