Right, a Vattel-style NBC interpretation wont care where Obama was born, so long as it was to a foreign parent, he wont be NBC by that definition.
I find this amusing. To paraphrase you...
Hence ... if not Honolulu, where?
Hence ... if not Vatel, whom?
Meaning, where did the idea of natural born citizen come from if not Vatel? The FF didn't just pull it out of a hat and it had to come before the cases you cited.
Remember..."Resort must be had elsewhere to ascertain that."

“Meaning, where did the idea of natural born citizen come from if not Vatel?”
The answer/argument from the other side is “English common law” and Blackstone. It’s the line of reasoning used in Wong Kim Ark.
“it had to come before the cases you cited.” It did indeed, and in many relevent cases, English rulings and Blackstone were cited.
