The naturals have only one 'end number' that is itself a natural, the first.
Every other natural but thate first is between yet other naturals.
So the set is complete as a set, and a well ordered set, but not as a set with a last member, at least not when using the usual ordering on the naturals.
But it appears that these simple facts, which seem fairly common and obvious to me, are beyond WM's grasp. --
