There are some conflicts in the original newspaper article. It says that Mr. McClure obtain a US Passport from the US Minister in London based on his being a "native citizen". But that the US Minister in Paris wanted him to provide more information about South Carolina laws. You have Mr. Rodman say that all he needed to be was born in the US and you have "Publius" saying that is not so.
So as you pointed out earlier if everyone agreed there would be no need for a Constitution.
