It's you who are still making confusion, infinite sets as only completed sets is one thing, the uncountability of the reals is another, and completed sets is not in fact Cantor's setting, despite overloads on terminology: Cantor didn't use an extended set of naturals as the domain of his functions. Then, whether extended sets (and non-well-founded ordinals? Oh how I wish people would also concentrate sometimes on *matters of fact*, the ones that count), change anything to the validity of Cantor's arguments is just beside the present point, although I would guess it does not, really, not just by itself.
