[The Sons of Liberty]

Well I would like to see a Constitutional Amendment that limits Federal ownership of lands within a state to no more than 20% of the total land mass.

No need. It is already there - "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 Constitution says nothing about the Federal government owning or controlling land. Another amendment won't do any good with a regime that ignores The Constitution anyway.

Except the government ownership preceded the states

Actually Article 1 section 8 specifically enumerates the powers of Congress with regards to owning land.
