I disagree. The second amendment is a doomsday provision assuring our right to protect against tyrannies, including abusive government. Essentially giving us the ability to self-defend our rites and state of being free. I think the smart people might call us, the armed citizenry, "non-state actors" in this scenario.
The second amendment does not limit your right to be arms for that purpose, but specifically enumerates it. In my opinion it is enumurated because the founders new it there would always be efforts to undermine it.
