Because he did not. It does not even make sense to say "disproved ZFC".

Every integer can be named. Every rational number can be named with
two integers. Nothing else satisfies the definition of "rational
number".

In constructive mathematics what cannot be constructed (of "found") does
not exist.

It seems that you don't have coherent opinions abot the binary tree.
At least your presentation has been incorerent.
