The set of rows and the set of columns are both the size of ⋃{F} and each other.

Yes, that is potentially infinite.

The set of rows, the set of columns, and ⋃{F} do not change.

Then it would need to contain ℕ, as an infinite FISON.

Nah. Then it would be finite.

No further rows would be needed. Actually, the first column is N.

Then your logic allows lossless exchanges with losses. Not acceptable.

Only in the limit of the permutations, which may not be a permutation
itself.

There is no limit in counting if countable sets are really countable.

Bravo, you wilfully misunderstood „limit”.
