This line of reasoning is really very silly. I can be looking out for my young child by choosing not to put them behind the driving wheel of my car.
There are both stupid and malicious people in the world. If you have a tool that you believe may be genuinely dangerous in the hands of the wrong person, it is not the smart thing to do to give the public unrestricted access to that tool. Do you think it would be sensible to give every individual on Earth a nuclear weapon to do whatever they want with?
