You’re just wrong. The Constitution must be interpreted through the lens of its creation. The context is being a servant for the states. If it is doing something the states can do for themselves it is violating the tenth amendment and the reason for its very existence. This is not just easily proven by doing a little research, it is self-evident by what we are experiencing today.
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.
