Take it from a lawyer: Do not argue with them. Pilots and ship captains are special. Their word is law.

A lot of those rules kick in only after the door is closed, or when the aircraft pulls back from the gate.

True, but a pilot can leverage that later power by not taking posession of the plane. Door stays open, airline cancels flight and everyone is now a trespassor and must get off.
