Hand-waving hogwash again. There is only _one_ set of all consecutive
finite whole numbers starting from 1. But there is an infinite number
of finite set of consecutive finite whole numbers starting with 1.
The set of _all_ consecutive finite whole numbers is not one of them.

Of all finite sets of consecutive whole numbers starting with 1. But
the set of _all_ consecutive whole numbers starting with 1 is not one
of them.

It is trivial to show that such a number does not exist.

> Do you know what the size of the set of finite naturals is?

It is trivial to show by induction that it can't be a finite natural.

> No. But, you know those two numbers are the same number,

Guffaw.

One does not exist, and the other is not a finite number. There are
frameworks in which it is a particular infinite number, though, that
labels the equivalence class containing the set of natural numbers as
one as its elements.
