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
that can solve all solvable problems?
 

When the essence of the change is to simply reject expressions
that specify semantic nonsense there is no reduction in the
expressive power of such a system.
