Further, if you studied the history of the naturalization acts you would find that the 1790 act was much criticized at the time as an attempt to alter the Constitution without amending it and, therefore, being of doubtful constitutionality and that, as a result of this concern, in 1795 Congress amended the act with a successor act and took the word "natural" out.
Neither the Framers nor anyone else had the power to bypass the formal Amendment process and change the Constitution. A statute is not the Constitution and cannot change it. It is precisely for this reason that Congress changed the act in 1795 to make clear that it had not sought to define what was intended by the Article II language.
Yes, the naturalization act of 1790 was replaced by 1795, who also was exercising their enumerated constitutional authority. And that act was repealed and replace and so on and so forth until we get to the current law as expressed in Title 8 section 1401 - Citizens at birth.
