You are seriously wrong.

You should have noted that this was an ironic reply. But in order to
avoid machines and undecidabilities:
The set of constructible numbers is countable. Any diagonal number is a
constructed and hence constructible number.

You still do not understand. Any constructable list of constructable
numbers gives a constructable diagonal number, so any *constructable*
list of constructable is necessarily incomplete.
