Is an atom RITSIAR? Is a quark RITISIAR?
The point is just that IF you survive "in the RITSIAR" sense, with a
digital (even material, if you want) brain, then materiality has to be
retrieved by coherence or gluing property of immaterial computation,
or there is an error in the UD Argument.

Again, if that is true, there must be something wrong in the UD
Argument. Which one?

The point is that Platonism is in the conclusion, not in the hypothesis.

Why do you want the UD to exist somewhere? Does prime numbers need to
exist somewhere to exist at all?
Does the physical universe exist somewhere?
The UDA reasoning is, in a short way: Comp -> Platonism. (In your
sense of platonism).
If you believe Platonism is false, then by the UD Argument, you
believe that comp (i.e. YD + CT) is false, or you believe that there
is something wrong in UDA.
What?
Let me ask you that question precisely.
Is it a problem with the first person indeterminacy and its invariance
properties? That is, is it a problem in the first sixth steps: UDA 1--6.
Is it a problem with UDA-7. Where the indeterminacy domain, still
material, is infinite?
Is it a problem with UDA-8. Where the indeterminacy field become
(sigma_1) arithmetical?
(sigma_1 means here a very tiny part of arithmetical truth, actually a
verifiable part which is common to intuitionist and platonist (in the
weak sense of believer in classical logic, sigma_1 = machine turing
accessible, in some sense.
