Forgive me. Its a long thread.
Where have you said how people will be prevented from access to nuclear materials and centrifuges?
You can't because it's already been done. It's impossible to be perfect. You can be induced and influenced to not want something. You can never prevent it, unless the laws of physics says it's not possible, and even then I wouldn't hold my breath.
Fred you already made clear that, in your ideal world, the nukes going off is just part of what we have to put up with. And under the present system, its not an issue because as you said, regulation works in preventing nukes but it restricts your freedom.
I asked Moonshadow his position.
