It's a bad argument for banning things but it is a perfectly correct argument for pointing out the the real cost of something. Cars kill people. We should not pretend that cars are safe, we should make a rational decision and come to the conclusion that the cost is worth the freedom of transportation.
You'r argument would be a valid analogy if I were suggesting that we make it illegal to tell anyone your location (or any other "private" information). I am only pointing out that privacy is valuable and we should count the cost if and when we give it up.
Should we stop people from using cars, because vehicles are used by drunk drivers?
