That is effectively true for all but "small" sets.

One rarely sees sets of 100 or more members that lists all members

individually. And the difficulty in actually listing increases with the

size of the set to become effectively impossible well before actual

infiniteness.

There is not now, and almost certainly never will be an up to date and

accurate list of every living person on earth at any particular moment.

But at any fixed moment such a SET actually exists, even in WMYTHEOLOGY.

Thus WM's pseudo-set-theory" crashes and burns.
