Your hypothetical was made citizen of a State under the Articles Of Confederation. The United States existed but not as currently constituted. All US citizens were disputed by England to be its subjects, leading to actions on the high seas such as impression of men in service to the US Navy, which in turn led to the War Of 1812, upon the conclusion of which the matter was settled. England had no claim upon US citizens.
“Your hypothetical was made citizen of a State under the Articles Of Confederation.”
So the Founders would have considered the foreign-born, naturalized, US citizen/British subject eligible to be president if he could get himself elected?
“All US citizens were disputed by England to be its subjects”
Not strictly true. Only those ex-British subjects who became naturalized US citizens after the 1783 Treaty of Peace were subject to impressment.
