If six people shared a house and two of those individuals decided to start enforcing how the others should live their lives, set limits on what chemicals they could put into their bodies and what words were allowed to leave their mouths the remaining 4 would be like 'fuck you'! It's only the threat of force like you mentioned or even violence that makes us adhere to governmental principles otherwise we'd be like those 4 hippy housemates and we'd be telling the government to go fuck themselves.
