No, that's a (mostly) fair point. I'd distinguish between objects whose dangers are obvious and those whose aren't. The danger of hammers is obvious. You know to treat them safely, and so there's comparatively little trouble. The possibility of having an untreatable needle stuck in your throat unless you use your tools in the right order is rather less so. I didn't say anything about banning unsafe objects, however. I think there's a case to be made for it if they're easily replaceable, but that's not the point I put forward.
