I dispute that "actually existing" and "true" are coherent, meaningful notions in any absolute sense.

In mathematics, it's irrelevant whether something is "true" or "false" in some absolute sense (whatever that might mean); the notions that matter are tautology and contradiction. You can ask whether a mathematical object is an accurate model of some aspect of the physical universe, but then it's an empirical question for science, and you've moved outside the realm of pure mathematics.
