While f(n) = 1/n, defines f(n) for each n which is a member of N, it does not define f(N), since N is a member of N.
Just another example of WM's logical and mathematical incompetence.

No, you don't. The number of things about mathematics that you make a point of not seeing is far greater than the list of the few things you do understand about actual mathematics, rather than the ersatz matheology you propound.

That infinitely many objects are not in any of an infinite increasing sequence of finite sets does not imply that there cannot be infinitely many members in the union of all those sets.
If each set in any infinite sequence of sets contains only one element not in any previous sets of that sequence, then both the limit set and the union set will contain infinitely many objects, at least everywhere outside of WM's incestuous matheology.
