Jason,
This initially interesting post of course exposes fundamental flaws
in its logic and the way that a lot of people get mislead by
physically impossible thought experiments such as the whole
interminable p-clone, p-zombie discussion on this group.
First there is of course no physical mechanism that continually
produces clones and places them in separate rooms, nor is there any
MW process that does that, so the whole analysis is moot, and
frankly childish as it doesn't even take into consideration what
aspects of reality change randomly and which don't. Specifically
it's NOT room numbers that seem random, it's quantum level events.
If anyone is looking for the source of quantum randomness I've
already provided an explanation. It occurs as fragmentary spacetimes
are created by quantum events and then merged via shared quantum
events. There can be no deterministic rules for aligning separate
spacetime fragments thus nature is forced to make those alignments
randomly.
But sadly no one on this group is interested in quantum theory, only
relativity, and far out philosophies such as 'comp'.
This list started from QM and Everett-QM. Then comp generalizes
Everett embedding of the physicist in the physical reality, to an
embedding of the "mathematicians" in arithmetic, with an indeterminacy
occurring for a similar reason.

If you read carefully it assumes a single real present moment self
that has the experience of being in one room or the other.

I came upon an interesting passage in "Our Mathematical Universe",
starting on page 194, which I think members of this list might
appreciate:
"It gradually hit me that this illusion of randomness business
really wasn't specific to quantum mechanics at all. Suppose that
some future technology allows you to be cloned while you're
sleeping, and that your two copies are placed in rooms numbered 0
and 1 (Figure 8.3). When they wake up, they'll both feel that the
room number they read is completely unpredictable and random. If in
the future, it becomes possible for you to upload your mind to a
computer, then what I'm saying here will feel totally obvious and
intuitive to you, since cloning yourself will be as easy as making a
copy of your software. If you repeated the cloning experiment from
Figure 8.3 many times and wrote down your room number each time,
you'd in almost all cases find that the sequence of zeros and ones
you'd written looked random, with zeros occurring about 50% of the
time. In other words, causal physics will produce the illusion of
randomness from your subjective viewpoint in any circumstance where
you're being cloned. The fundamental reason that quantum mechanics
appears random even though the wave function evolves
deterministically is that the Schrodinger equation can evolve a
wavefunction with a single you into one with clones of you in
parallel universes. So how does it feel when you get cloned? It
feels random! And every time something fundamentally random appears
to happen to you, which couldn't have been predicted even in
principle, it's a sign that you've been cloned."
