How do you imagine this plays out of the Left is awarded complete dominion even when they lose the election and defy the American people?

Communism reliies on compulsion, surveillance, punishment & central authority. It claims to be “rule by the people, for the people” Without individual rights, “the people” cannot consent. There is no mechanism to distinguish cooperation from obedience. The collective becomes an abstraction weaponised by those in power. The moment individual rights fade, "the people" becomes a mask for authority. Communism cannot operate without suppressing individual rights. "Fumbling some key liberties", is the Communist reset. Wake up Neo.

the question becomes: does The State somehow have a legitimate claim to the entire physical territory it says belongs to it? (in which case, we'd be sort of "tenants" residing under an agreement, and breaking that agreement or plotting to undermine it would be morally problematic)
