I understand your position, but disagree with it, which is why I used the hypotheticals I did.
You are not harping. You are making an understandable case on a potentially complicated matter. It gets more complicated when Common Law and Natural Law are brought in, as even Natural Law requires a judicial framework (e.g. laws defining the boundaries and jurisdiction of a nation). Also, while the terms “citizen” and “subject” are analogous, they are certainly NOT identical.
I understand being Natural Born the same way the traditional Catholic Church sees annulments. It is a declaration that a valid marriage did not take place. However, even though it didn’t, yo still have to get a formal declaration to get that fact recognized.
Thank you for your clarification and understanding.
