The basic error here is the assumption that a law can redefine a Constitutional term. That would be like one party to a contract deciding that "property" did not include the house that contract was in reference to.

Besides which, 8 USC § 1401, doesn't even contain the term "natural born" or "natural born citizen", so how can it be attempting to redefine it?

The term meant something in 1787 to 1789, when the Constitution was written and ratified. For the "contract" to mean anything at all, it must mean the same thing today as it did then, at least for purposed of that section of the Constitution.

Our job as citizens today, is to determine what the meaning was and is. It will also be the job of the Supreme Court, should the court ever take up the issue.

Oops, meant 1787 to 1788. Although Rhode Island ratified much later, after being threatened with treatment as a foreign nation.
