That seems to me an odd way to put things. It seems
to remove from the field of math any issue of why some
axiom sets are more interesting than others, or even the
tie between axioms and result. In other words, you're
writing as if stating a result lies properly in math, or rather
properly within math-ZFC, but that stating "result x is
proved in ZFC" is not within the field of math. My
experience is that most mathematicians are able to
abstract back to where axioms also are objects, not
solely principles. ;-)

Nor would I call axioms are arbitrary. The set theories
we get are a result of the project to put analysis and
topology on rigorous basis, a fairly famous historical
