Wouldn't that alternative be one in which there are only a finite number of possible persons?...e.g. materialism.

That's true, it is not a contradiction. However, from a Bayesian
perspective one must favor the alternative that gives one's a
existence a non-zero measure.

hmmm, my interpretation is that in platonia, all computations, all the

computations have been performed in a timeless way. If so, it follows
that the state that corresponds to my mind at this moment has an
infinite number of instantiations in the UD (regardless of some
arbitrary "current" state of the UD). In fact this is the only way I
can make sense of the reversal, where physics emerges from "the
infinite computations going through my state".  Otherwise, I think the
physics that emerges would depend in a contigent way on the
particulars of how the UD unfolds.

Whether the infinities involved with my current state are of the same
ordinality as the infinitie of all computations, I'm not sure. But I
think if it was a "lesser" infinity, so that the probability of my
state being instantiated did approach zero in the limit, then my
interpretation above would imply that the probability of my existence
is actually zero. Which is a contradiction.

You may be right.  I we think of the UD as existing in Platonia, then we
might as well think of it's computations as completed.

I don't think that your probability having measure zero implies you can't
exist.  The number pi has zero measure on the real line, but it still
exists.

Of course that also implies that "you" are never complete, since at any
given state in the UD there still remain infinitely many computations
that
will, in later steps, go through the states instantiating "you".

Not zero, only zero in the limit of completing the infinite
computations.
So
at any stage short the infinite completion the probability of "you" is
very
small, but non-zero.  But we already knew that.
