If not defined in the Constitution, like treason is, then they are defined by law. And the current law does not define natural-born citizen the way you do.

I guess you'd be OK with Congress passing a law making writing on an internet forum neither speach nor press, and thus subject to anything Congress wishes to do with it.

Laws cannot define any Constitutional term, for that would allow them to change the Constitution.

If you mean "case law", there is no case law directly on the subject, for the only time the distinction matters is for eligibility to the office of President.

Of course not, what a ridiculous suggestion.

Agreed. Show me where the Constitution defines natural-born citizen.

I wouldn't agree with that. I think there are several cases which clarify the question.
