Why should it work less well for the aleph_0 steps of well-ordering the rations by magnitude?

Every step is well-defined such that we, you and me, when starting with the same enumaration of |Q, will up to step n (for every n) get the same result including as many rationals as we like. And if we apply the axiom we get that for all steps.

Mathematics is an ideal theory that doesn't not necessarily correspond directly with reality.

Matheology is in direct contradiction with reality, science, and sanity.

Yes, but never matheology which is even less scientific as astrology.

Every application of the axiom of infinity generates a super task. Enumerating all rationals is but one example that is so simple that most people do not realize its character as a super task.
