The whole of Lincoln's argument can be summed up in this: the States are not allowed to leave the United States.
If that were taken as true, then they must have been citizens of the United States, transitively through their citizenship in their State…
What it also means is that the Civil War was Treason, on part of the federal government due to the definition in the Constitution:Treason against the United States, shall consist only in levying War against them, or in adhering to their Enemies, giving them Aid and Comfort.
Washington used federal troops against the Whiskey Rebellion.
Other examples The “Dorr Rebellion” in Rhode Island in 1842; the Abolition disturbances in Kansas between 1854 and 1858; the railroad strikes of 1877, extending through West Virginia, Maryland, Pennsylvania, Ohio, and Indiana; the Chicago strike of 1894; the San Francisco fire of 1906; the West Virginia coal strikes of 1921; and lastly, the “Bonus War” of 1932.
