If you will pardon a socio-politico comment :-) this is a common thing. Ban the tool when the tool itself is harmless, rather than the subset of its actions which are the real evil. I am especially familiar with this since I live in California and like to shoot guns, but it applies to all manner of things. It is a quite common human failing. I sometimes wonder of all the OSHA labels we get in the USA (do not step on the top steps or the backside of a ladder, do not use electrical devices in the bath) are a misguided attempt to get around that, but that's about when I decide that politicians are evil and my brain switches to a less annoying topic.
