The quirk is that in the UK you’re not a free man but only a subject and in the end the crown owns everything and now fuck off, filthy peasant, before the king sends his men.
This is true in practice pretty much everywhere governments exist though, it's not really a monarchy versus republic thing. The stick is no less painful if it's called "society's stick" rather than "the King's stick" if the government of the day decide to beat you with it.
Is this really different than any other country? Any government (at least in uncontested territories) can come in and tell you to fuck off, and there's really very little you can do about it.
Quite the opposite. You ask the state to use their monopoly on legitimate use of force to enforce your rights in accordance to law. What you imply is a failed state. The state must maintain the legitimacy of that use to maintain consent of the people, that or it slides into far less prosperous configurations.
Being in a far less prosperous (in a meta sense) configuration is surprisingly not as big a deterrent as one might expect, especially if you are making them angry or the official involved would
get far more prosperous (in a direct, concrete way) along the way.
