Those are definitions, not derived. Maybe they're "wrong", of the true nature of the continuum. Yes, many perfectly reasonable theorems are derived from them, both axiomatically, and matching intuition. I'm not the first to suggest Cauchy insufficient, where of course I will agree that Cauchy (or Cauchy/Weierstrass as it were) is a perfectly reasonable framework for analytical results, just not closure of all results.
A well ordering of the reals doesn't have uncountably many points in their natural order.
