That can only hold for definable x, not for all.

Poppycock!  You'll have to do better than that to provide such a

I do understand.  I understand that what you are writing is not maths.
I'm trying to explain to you why.  I've already proved that there are no
"undefinable" natural numbers.  So assertions about them can not make any
sense.

That won't stop him. A set is a collection of well-defined objects, meaning we must be able to determine if an element belongs to a particulr set. He simply can't have a set of undefined or undefinable elements. But that doesn't stop him either. :)
