I have been thinking about gun control, my starting point was “why is it OK to have a gun but not a nuclear weapon”, and I have read a lot of the threads on the topic in these forums and the most convincing argument I found was this article by Walter Block:
http://www.walterblock.com/wp-content/uploads/publications/theory_gun_control.pdf
I can accept, within Block’s geo-spacial dimension, that a gun can be targetted as a weapon of defence at only an aggressor, whilst a nuclear weapon cannot. I can also accept (just) that the ownership of a nuclear weapon can be considered as a threat in and of itself without use, or threat of use, because its lack of alternative peaceful uses mskes its existence a threat of violence.
But, on reflection, I don’t think this is really the issue, because what if I don’t have a nuclear weapon, what if I have a new energy device that powers my home. The only problem is that if I knock it over it will explode with enough violence to destroy the entire planet.
My device has a perfectly legitimate use, so Block’s arguments against owning a nuclear weapon do not apply.
The issue in this case becomes the trade off between the right to own property and the risk of causing violence to others.
I would argue that if my neighbour installed such a device it represents as much of an immediate threat of violence to me as if he pulls out a knife and lunges towards me and I have the right to use force to protect myself and my property.
I know that Rothbard says that threats of violence must be immediate, etc, but perhaps the degree of immediacy is moderated by the severity of the potential threat. It might be necessary to wait for a man with a knife to lunge at you, but if a man starts setting up a gatling gun in a school yard, is it really necessary to wait for him to point at the first child before having the right to intervene.
Do I have to wait until my neighbours device is in the process of being knocked over, before I have the right to try and prevent myself and everyone else being blown up ?
If we adopt the view that it is not simply the immediacy of the threat but its severity that determines the right to self defence then perhaps both the weapon and the dangerous energy device scenarios could be dealt with.
