You beg the question. Numbers are not physically real does not entails
that numbers don't exist at all, unless you define "real" by "physical
real".
The question you should ask is: "are number sufficiently real to
explain why some of them believes in a physical reality". My answer,
which I agree need some amount of work to get through, is "yes".
"Existing" in the standard mathematical meaning of existence is enough
to explain why a "stable and lawful "illusion" of physical reality"
exists, again in that mathematical sense. Recall that the UDA explains
why, assuming comp, a turing machine cannot distinguish the
"physical", virtual and "arithmetical" aspect of any reality.
Perhaps one day we will find a way to make those distinction. My work
proposes a transparently clear way to observe that distinction if it
exists, but then that would be a refutation of (standard) comp.

The AUDA hypostases explains this, including 4. Wait a bit perhaps, or
read my papers.
