Well, I'm assuming you're talking about minarchism (since, in an anarchist society, the second amendment wouldn't exist).
Well, I'm technically an ancap (relatively recent convert, but all the same

), and I don't see why the second amendment couldn't exist in an ancap society (mind you, it probably wouldn't be necessary, but that's a different issue entirely.) That said, I don't see how whether or not we're talking about minarchy or anarchy makes a difference here in particular.
However, I don't believe that roads should be privatized. People have the right to travel, and the only viable way to travel today is on roads. So not ALL property should be privatized, IMO.
I disagree. I think HB34 presented my objection better than I could myself, so I'll simply leave you with his words.
But I don't think that walking around with grenade launchers ANYWHERE should be okay. I understand why we have the Second Amendment, but I think it would just be stupid to let people have ANY weapon with NO restrictions. The difference between an assault rifle and a rocket launcher is this:
With an assault rifle, yes, someone could kill 10 people, for example, before someone pulled out a gun and killed them. With a rocket launcher, someone could kill THOUSANDS from even just a rooftop before anyone could get to them. No matter what gun restrictions we have, or lack thereof, there will be gun crimes, but we need SOME, just like how I feel we need SOME government.
I'm willing to leave the debate of minarchism vs anarcho-capitalism for another time, but I don't see how this makes a difference here. Why are 10 deaths an acceptable price to pay but not 10,000? There's no rational line to be drawn here. Its completely arbitrary and stupid. With a nuke there actually is a logical reason, its not because hundreds of thousands MIGHT be killed, but because the weapon literally CAN'T be used in anything but a malicious manner.
All weapons can be used that way.
Yes, which is why the poster you responded to's argument is stupid, just like he is. The distinction for me is not whether a weapon can be misused. Any weapon, or indeed, anything, can. My argument is based on whether a weapon can be used acceptably.
Say you hunted me down and killed me with a machine gun (I know you wouldn't, but just for the sake of my argument.) A family member responds by hunting you down and killing you with a machine gun. Or, I use my machine gun to defend myself and I kill you before you can kill me. Ignoring issues of proof and courts and such, this is an acceptable, retaliatory used of a weapon.
Alternately, say you attack me by shooting a nuke at my house, and I respond by nuking yours. Despite the fact that my reaction seems proportionate, this is NOT a libertarian means of defending myself. You murdered thousands of people (at least) and I responded by murdering thousands of people (again, at least.)
My point is that there isn't a libertarian way to use a nuke to defend yourself or to retaliate against a criminal. If this is the case for other weapons, than its OK to ban them. But for most weapons, this is not the case.
I asked you why you believe this.
I don't believe private road owners would trap people in a truly free society, as it's not in their rational self-interest. Besides, the government can do the same if they decide they don't like you or want to build a project around your place...or even take your place outright via Eminent Domain. I've heard of people being forced to move because their cities allowed airports and other nuisances to be built too close to the residential zones.
Agreed.
Wait. Didn't Dr. Gaius Baltar acquire a nuclear bomb (from Admiral Adama) to construct a Cylon detector in the TV series Battlestar Galactica?
And. Countries that have Nukes seem to enjoy more homeland peace than countries that are "nukeless".
That's true. Also, in reality, governments act in rational self-interest (Note that by saying this I am not suggesting that their existence is morally justified). I'm not suggesting that wars to disarm nuclear powers, especially by other nuclear powers, are justified. And yes, nukes do act as a deterrent. There's nothing libertarian about this fact though. The threat of nuclear retalitation, while it might protect one from being attacked, is still a threat that cannot be carried out without violating the NAP.
