Lastly, I would point out that there is nothing natural about statutorily created citizenship, either at birth or after birth. As Michael Ramsey pointed out in his essay, “The Original Meaning of ‘Natural Born’: “In general in eighteenth-century legal language, ‘natural’ meant the opposite of provided by statute.” (natural rights, natural law, natural born)
I would also point out that in general, a general clause (i.e. Citizens of the United States at birth — 14th Amendment) can not govern a specific clause (i.e. No Person except a natural born Citizen — Art. II, I, Cl. 5) unless Congress has specifically stated via its constitutional authority that “all citizens at birth are natural born citizens” — which, in, and of itself, would be unconstitutional, as positive law cannot create natural law — the court MUST give each clause a separate legal effect.
Simply put: “While all natural born citizens are Citizens of the United States at birth, statutory Citizens of the United States at birth are not natural Citizens of the United States at birth but naturalized U.S. Citizens at birth.
You cannot be a naturalized citizen at birth. Natural and native come from the Latin root for "birth." Citizens who did not need to be naturalized are natural born citizens.
