Really? So it is true that, say, Peano arithmetic is

Why would you say that? The axioms of Peano (I
prefer to say Dedekind-Peano) are certainly self-
consistent.

If I venture to try and interpret what you mean--that
(as Godel proved) no system of axioms is strong enough
to prove its own consistency--such does not obviate
anything that I said.
