It is far from clear that a theory of that kind can express all arithmetic

He can only think in primitive logic systems that can't reach the complexity needed for the proofs he talks about, but can't see the problem, as he just doesn't understand the needed concepts.

The topic of the discussion is completeness. Is there a complete system

If NOTHING ever stipulates that 3 > 2 then NO ONE can
possibly know that 3 > 2 leaving the finite string
"3 > 2" merely random gibberish.
The ultimate foundation of all truth that is made true
entirely by other expressions of language is these other
expressions of stipulated truth.
