That law is not based on thorough data. Even a person with a sky high IQ can't destroy the world easily. You need access to stuff that is not easy to get. My guess is that developing a new lethal virus or bacteria that is very infectious, is the easiest way, but even that requires a lot of high tech out of reach of most people. Or hacking into systems that control nuclear missiles, but I think these have "air gaps".
