I find this argument to be pretty useless by now. We all live in a modern society. You can order a crisper-cas do it yourself chemistry kit for your home, your devices are powered by potential electric hand grenades and you can write software in your basement that could cripple the worlds infrastructure for months. Everyone can create a potential doomsday device in his/her basement. And with every physics discover, the likelihood for ease of access to the world-burning zippo is dropping faster and faster. And its a good thing. Any high energy ray in orbit could be gunned down with railguns or destroyed with reflection. I know its fancy to pretend that security is something real, not just a safety dance, ever after 9/11 - so in order for everyone to feel safe- we are going to do cavity searches on astronauts from now on.
