It's really comes down to one of the foundational concepts the founders put forth. "Is this worth straight murdering a motherfucker over?"
Simply put, the Bill of Rights used to be a list of things we would kill them over. In the modern day, we have decided that the current status quo isn't worth the bloodshed. Natural law says that violence is the supreme authority from which all other authority is derived. We are not exercising our authority in the margins, so they do in our absence.
Ask yourself why you, personally, haven't sniped a scumfuck politician off the balcony of his mansion and you will have your answer.
