I agree... but to be honest, I think it's ok to regulate what arms can be privately owned.Shall. Not. Be. Infringed.
It is not the purview of the FedGod to regulate intrastate transfers of private property or contracts.
If you want to really go down the rabbit hole then it would be possible for there to be private armies with tanks and war planes. I have watched to many movies too think it's a good idea for Google (or some corporation) to have an army. Serious. If you allow private citizens to have tanks it'd be tough to stop private entities to have them in mass.
