This last is false.  What maths discusses also includes things which
haven't been proven, and indeed can't be proven.  For exampe proof by
contradiction discusses such things.

Is that your definition of "provably well-defined"?  If so, I suggest it
is not a useful definition.  "Every real number between 0 and 1 which
isn't rational" is provably well defined, by any reasonable
interpretation of that phrase.

Yes, demonstrating that the list cannot have been complete in a well
understood sense.

That's not what the diagonal argument proves.  This is that a supposed
countable list of all real numbers cannot exist.  Hence the real numbers
are not countable.

You're confusing two distinct meanings of "domain of discourse": (i) the
domain of proofs; this is indeed countable; (ii) The entities these
proofs deal with, which need not be countable.

If you accept the axiom of completion (which distinguishes the real
numbers from countable subsets of them), you are compelled to believe in
uncountable sets.

Cantor rigorously demonstrated the existence of non-countable sets, based
only on the representation of numbers as arbitrary decimal expansions.
If you wanted this theorem to be false, you'd have to somehow do away
with decimal expansions of numbers.  But why would you want this?

You could say the same about any mathematical argument.  As for truth and
reality, that's more the domain of philosophers than mathematicians.

Fact?  That assertion is screaming out for a citation.  As far as I am
aware, Cantor's arguments are now universally accepted by mathematicians.

Fermat's Last Theorem has been part of maths for several hundred years,
and up until ~20 years ago one had the choice to believe it or not.  I
think you have mis-characterised maths.  There are many mathematical
topics which one has the choice to believe or not (areas of research).
At another level you can chose to "believe" (or not) the axiom of choice,
for example.  You'll get somewhat different systems of maths depending on
your choice.

Set theory is part of mathematics.  Not all of maths has important
connections with real life (whatever that might be).
