The union of all FISONs does not cover ℕ. Otherwise Cantor's theorem

Cantor’s theorem does not force a necessary FISON. We already established
that no finite set of FISONs suffices.

 Cantor's theorem concerns also infinite sets. Without a first element the set is empty.

No, without a first element, the set doesn't exist.
Your "Set of Necessay FISONs" doesn't exist in anythin working set theory, just your Naive Set theory that has exploded your brain into smithereens from its inconsistancies.
