I'll find the flaw in UDA in due course ;)

If the UDA is sound that would certainly refute what I'm claiming
yes. I want to see how physics (which as far I'm concerned *is*
geometry - at least I think pure physics=geometry) emerges *purely*
from theories of sets/numbers/categories.
I base my claims on ontological considerations (5 years of deep
thought about ontology), which lead me to strongly suspect the
irreducible property dualism between physical and mathematical
properties. Thus I'm highly skeptical of UDA but have yet to property
study it. Lacking resources to do proper study here at the
moment.... :-(
Time will tell.
