We've just been through (again) finding there is no contradiction
between physics and arithmetic.
I think you need to be more precise. The contradiction is not between
physics and arithmetic, but between computationalism and physicalism.
Your answer seems to be that physics can be an illusion of digital
thought, therefore primary physics is otiose.
Just reread the quote above. Or reread may old posts where I say the
exact contrary of what you say here. If computationalism is true, then
physics cannot be an illusion of digital thought: on the contrary it
has to be precisely a sum on an infinity of digital illusion/
histories, which is hardly emulable by a digital computer, but is
first person recoverable thanks to the fact that the first person is
unaware of the delays made by the UD in arithmetic.
But thought can't be a consequence of physics because....well you
just don't see how it could be.
Not at all. It *cannot* be. You need magic to single out anything
capable to select the computations better than the indeterminate
experience on all relative continuations. The problem is not with
physics, but with physicalism.
