Sorry, you have not refuted any of the facts. When I assert that the US Government owns the land and even provide a history of how by treaty, by acceptance into statehood and by building useful buildings, I am showing facts to prove the position that the US Government owns the land.
You have responded with what? Conjecture that the US Government should not own the land. Despite the government having met the constitutional requirement of useful buildings? Your argument that it is a requirement for the government to own the land and even that point has been proven to be fulfilled.
Please enlighten me how your conjecture some how proves that the US government does not own the land in question.
It's not conjecture. It's the plain text of the Constitution absent your silly editing.
