The only sort of existence for which we have concrete evidence is
physical existence. We can understand imaginary things, but we have no
direct evidence for their existence -- certainly not for their physical
existence.

There it is again. Where is your evidence? Or are you led by your faith?

It's hard to see how physics can be self-consistent

Maybe it is because the self-consistency of physics is
what makes arithmetic possible.
Though admittedly that is a different point to
whether or not physics is "emulated" in arithmetic.
True. But no-one has yet emulated any physics in
arithmetic. All the we have is mathematical accounts of
discovered physical laws -- arithmetic based in physics.
I recently replied to someone on the FOAR list who expressed
a similar criticism:
Something has to "run" the math... ;) electricity or not.
Isn't this being a bit one-sided?
Physics can run itself, but objects in math cannot.
A physical universe can exist independently of anything
else, but a mathematical object cannot.
A physical computation can result in consciousness, a
mathematical computation results in nothing.
From where does such bias originate?
From experience as a physical being.
Your experience provides evidence for the existence of the
physical universe, but don't confuse this for evidence of the
non-existence of anything outside the physical universe.
You mean don't confuse it with existence of imaginary things?
