So what? Take any (uniquely operated) iteration and count the steps by whichever method you like  the result is isomorphic to N in whichever 'theory'. Some folks who 'feel incomfortable', like the asshole idiot WM, when one defines a limit to that sort of operation, thus are unable to comprehend that abstraction, might go see a doctor or invent alternative theories  anyway, whoever drivels about something like 'physical existence' of numbers is just a plain idiot, hopefully a kind one.
