Since the number of natural numbers is not itself a natural number, that is a nonsequitur, despite standardly the conclusive statement is correct: indeed, a fallacy of relevance. Plus, the standard here is in question, so one should rather qualify statements as well as objections (not that WM ever does it, of course).

That there is no such thing as a _set_ N (i.e. a finiteinductive set, an "unfinished set") is a thesis of *strict finitism* already: <http://en.wikipedia.org/wiki/Finitism#Classical_finitism_vs._strict_finitism>
