If not, there is no possibility for a time variable in arithmetic

No it isn't, not in the sense being used here. The concept that is relevant in this
case is ontological priority. If you think emergence is temporal then you will get
very confused by discussions of the MUH (or even of how the universe arises as a 4D
manifold from the laws of physics)
Which law of physics gives rise to the 4D manifold? It is my understanding that a 4D
pseudo-Riemannian manifold was a basic postulate underlying general relativity -- if
that hypothesis emerged from anything, then it came from the fact that space-time was
observed to be a 4 dimensional structure. So the 4D manifold is not actually derived
from anything other than observation.
Kant made the mistake of thinking that Euclidean space was a necessary law of thought.
Observation proved him wrong. Maybe observation also proves the MUH wrong?
Observation can't prove anything wrong about a theory that says everything happens in
some universe. ;-)
Everything (consistent) happens in the mind of some machines, but the laws are in the
relative measure, provided notably by the logical intensional nuance brought by
incompleteness.
By "consistent" do you mean logically consistent; thus implying that no event can be
nomologically inconsistent? That is the same as denying there is any such thing as "laws
of physics".
