WM is the only one who equates the finiteness of all members with the
finiteness of the set of all members. Consicer the real inteval [0,1].

Does the finiteness of the members of that set establish the finiteness
of the set itself? NO!

But for any ordered set there must be provably a last member to prove
the set to be finite.

What it is called is irrelevant once its existence is established, and
it has been.

Actually, proper grammar, at least in English, requires that the term be
"infinite" not "infinity"
