“Article 1 Section 8 Paragraph 27 limits the amount of land the Federal Government can own in any one state to 10 square miles.”
Are you talking about this?
To exercise exclusive Legislation in all Cases whatsoever, over such District (not exceeding ten Miles square) as may, by Cession of particular States, and the Acceptance of Congress, become the Seat of the Government of the United States, and to exercise like Authority over all Places purchased by the Consent of the Legislature of the State in which the Same shall be, for the Erection of Forts, Magazines, Arsenals, dock-Yards, and other needful Buildings;
Ten square miles is not the most land the federal government can own in a state. That has to do with relocating the capital. The federal government is supposed to purchase land with the consent of the state legislature and only for necessary purposes which are specified in the constitution.
