I think this -- whether something should be illegal because it could be used to harm others -- isn't a particularly helpful way to frame things. I could drop a refrigerator from a crane onto the jerk who lets his dog poop in my yard, and obviously refrigerators and cranes shouldn't be illegal. OTOH, "you could set off an atom bomb, should atom bombs be illegal?" (Yes, for ordinary folks, obviously.) And "11 year olds could drive a car and have an accident, should 11 year olds driving cars be illegal?" (Yes, obviously.)

I think you have to look at from a broader viewpoint. The government regulates many things for a variety of reasons (public safety, mitigating negative externalities), and aside from libertarian cranks, I don't see anyone shaking their fists at the government for having seatbelt laws or food regulations or speed limits. It's not "because criminals could drive their getaway cars really fast" that we have speed limits.

(Perhaps that's actually what you're implying... not sure.)
