I need no law to make me a citizen, I am one by right of birth.
I reject your attempt to equate naturalization with citizenship in general.
Lets go through a simple thought exercise. Let set up two people Mr. A and Mr. B Both claim to be US citizens. One has his citizenship confirmed by US Law (Mr A) and one CLAIMS to be a US Citizen but there is no US Law confirming his citizenship (Mr B)
Who is in fact, a citizen? Not Mr B because the laws don’t support his case NO MATTER WHAT HE CLAIMS. In other words, the law/act/statute is there to direct the will of Congress on the government and control the behavior of government with regards to how it treats the People.
Since “natural law” is NOT BINDING on the US government, Mr B can shout and shake his fist, but he is NOT a citizen of the US until there is an established rule making him a citizen of the US. Be it by birth or by naturalization.
Let me ask you this, a citizen who was not a citizen at birth is called a naturalized citizen. What do you call a citizen who was born a citizen?
