There is a thing called enumerated powers. The Tenth Amendment to the Constitution does not alter powers specifically stated (enumerated) in the Constitution.
Article 1 section 8 enumerates the power of Congress to have exclusive jurisdiction in all matters whatsoever for both the District of Columbia and any other lands that the US Government owns. The 10th reads:
The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people
The first clause of the 10th is met by Article 1 section 8 therefor, does not apply.
Possessing the near entirety of a states geographic footprint
Is NOT a power that was EVER delegated to the United States (federal government). Sorry, you’re wrong on every level and proving yourself to be a tool for federal tyranny at every level.
