This is where I finally landed with this question - there’s too much vagueness and importantly no agreed definitions of what is and is not “reality” Math has no fundamental non-differentiable epistemology qua mathematics. As you said there is no meaningfully discrete, bounded “object” that can be used as a universal reference - so the fact of relativity means that even if maths were “real” I’m not even sure such a thing exists (who says the rules of the universe are uniform, or static as we’re only have a few centuries of poor observation) and if it does exist, if humans have the ability to identify it
