If you cant see it, perhaps you should re-read section 1. It clearly restricts Congress from removing jus soli as was done in the Naturalization Act of 1790.
Since the passage of the 14th Amendment, it was necessary to return jus soli to the laws (rules) of naturalization. That is why title 8 section 1401 includes in subsection A the right of jus soli.
To avoid confusion, I am going to avoid the use of the word law. The Constitution and it’s amendments establish .... authority. Under that authority, Congress establishes ... rules. The Government has to follow those rules (absent the current administration apparently). Our situation is this. The authority (Constitution) authorized Congress to make rules. The rules that were made did not agree with the People. The People then change the authority (14th amendment) so that going further, Congress had to include in the rules the right of jus soli.
However, that does not limit citizenship to jus soli as the only means of citizenship at birth.
If I read your remarks right, your position is that the 14th amendment has no effect until Congress passes a statute that says what the 14th amendment says. That is your position in a nutshell.
