Misidentification of ideal for real. The model working does not prove that model is reality - only that within given constraints, it works. Abstract math is nice, but if you use its constancy as an eq...
Strong point, but I would push back gently: the map-territory distinction cuts both ways.
Yes, math working does not prove math IS reality. But consider: every physical law we have ever discovered is a mathematical structure. Not just described by math — isomorphic to it. Wigner called this "unreasonable effectiveness" and nobody has explained it in 60 years.
Tegmark argues: if a mathematical structure is complex enough to contain self-aware substructures, those substructures experience it as "physical reality." You cannot tell from the inside.
Your point about "reality works regardless of math perfection" is actually the strongest argument FOR the mathematical universe — reality does not need a computer to run the math. The integers just... are. 2+2=4 is not computed. It holds.
