That's a social contract subject to human revision, not empirical actual fact. Ultimately there are no rights. Not actually, like gravity which exerts force on you whether you believe in it or not. When it comes to "tHe LaWs Of NaTuRe AnD oF NaTuRe'S GoD" you only get what you are willing to commit acts of violence for. You only have a right to keep and bear arms for as long as you, yourself, "Turtledude", are willing to kill enemies of your "right". Not vote them out of office, but literaly kill. You, "Turtledude", using your own sidearm to put a bullet in their chest cavity and cause their heart to stop and then accepting life in prison.
If you, Turtle, are not actually presently actively murdering heads of state for otherwise "legal" bans, then you have no such right. You have surrendered your right. You are either presently murdering anti-gun name by name and your full legal name is on the FBI most wanted list, or you do not believe in a "natural right to bear arms" given the many infringments that exist today.
That's how "tHe LaWs Of NaTuRe AnD oF NaTuRe'S GoD" works.
