July 4, 1776 was recognized (by the Founders, and all subsequent courts) as the point at which the Colonies ceased being British Subjects, and thereafter were United States Citizens.
This is not even debatable.
So I would suggest to you that if American Citizenship was created by the Declaration of Independence, then that document ought to have a very strong relevance to what constitutes the characteristic of citizenship.
The Articles of Confederation did not create US Citizens. The US Constitution did not create US Citizens. It was the Declaration of Independence which CREATED US CITIZENS.
It is not one of the documents/agreements listed by the Constitution as the Supreme Law of the land.
Why should we assume that the entire Congress is always populated by no-nothings who have no desire to ascertain the intent of the Founders? After all, they are the ones given the authority to determine the issue of who needs to be naturalized and who doesn’t.
So, it’s highly likely they’ve considered these things and simply disagreed over the years with opinions like those who don’t like blood-based natural citizenship.
