We have lots of reason to beeive that anything WM presents as a proof
that is not copied from soemone more competent, is incorrect.
Some of those reasons are the obvious flaws in logic that WM is know for.

Not at all. there is no reason why line n, for any n > 1, must be of
length >= n.
In decimal notation, one could start with 10 lines of length 1 followed
by 90 lines of length 2, followed by 900 lines of length 3, etc., and
never repeat a number.

But a "diagonal" need not be, and will not be finite.

The diagonal is already required to be infinitely long, so its length
need not change.
