Territories are not States. Once a territory has become the land of a State where does the federal government get the right to take State lands?
A State is sovereign. It is not willy-nilly of the federal government to take and give as it pleases.
Nothing in the Constitution grants the right of the federal government to take State lands.
You obviously have a reading comprehension problem.
The federal govenrment has the right to administer territories but not States. Try looking up the word “prejudice”.
The territory was created about 1804 ~ by the FOUNDERS ~ and United States land patents authorized to pay Revolutionary War soldiers were purchased from those soldiers and their heirs, consolidated into large tracts, and approved for sale by the Confederation Congress ~ and that practice continued on through Statehood. The last public lands (owned by the United States and the State of Indiana) in Indiana were located in the Limberlost region (a massive wetland South of Fort Wayne).
They were surveyed and sold in the early 1900s, nearly a century later!
The clauses I just cited for you secured the United States ownership of its own lands (which for all you knew might have already been pledged to somebody else, e.g. a Revolutionary War vet) and also the ownership of state lands.
Your argument leads off into a state being created and all other land titles being extinguished. I'm sorry ~ that just doesn't happen. Not now. Not then. Not ever if we can help it.
