On the contrary, ZFC is a deeply unlogical theory. It requires the
belief that uncountably many elements can be distinguished whereas
everybody knows that this is impossible even in ideal mathematics.
Further in ZFC the sequence
21., 2.1, 432.1, 43.21, 6543.21, 654.321, ...
has the limit < 1. In analysis the very same sequence has the
(improper)imit oo.

If analysis is based upon ZFC then we have a contradiction. If
analysis is not based upon ZFC then ZFC is irrelevant for mathematics.
