Sorry, that is not true. See the first acts of Congress
Which would have been naturalization.
You can tell me "that is not true", but it is from the same Supreme Court decision you cited yourself. It is from the "Wong Kim Ark" decision, which so many people think is the very last word on the subject.
You also don't seem to realize that the court is saying that an "act of congress" is "naturalization." Here, let me point out that part of the quote again.
A person born out of the jurisdiction of the United States can only become a citizen by being naturalized ... by authority of Congress... as in the enactments conferring citizenship upon foreign-born children of citizens...
This statement directly refers to "acts of Congress" which confer citizenship on foreign born children as "naturalization."
The Supreme court is pretty much saying that if you aren't born inside the country, you are "naturalized. " I don't see any wiggle room in their statement.
