Intuitively we know this. Setting speed limits to a universal 5 MPH and rigidly enforcing the rule is close to what would be needed to reduce traffic fatalities to zero. But most people love their freedom and mobility. They look at the risk of a fatal accident with the rules as they are and say it's acceptable. And when someone beats the odds and has one, we don't generally blame the laws. We say it's a tragic accident, which is a way of saying an acceptable risk has been realized for someone.
We should think the same way about a great many things. Things like aircraft bombing or child abduction are horrific, but low risk. The horror makes us incorrectly disregard the fact that the risk is low--possibly low enough, even, to be acceptable.
The problem is compounded by the political and human need to do something. Even if the risk is acceptably low and cannot be meaningfully reduced without draconian measures, people feel the need to bring it down by one means or another. So they do things that don't help. For show. For comfort. Out of confusion.
A bit of mathematical clarity and a willingness to label things mere accidents would be helpful. Considering the many men willing to give their lives in wars throughout history to secure better lives for their descendants, it would be a shame if we threw it all away for fear of a few accidental deaths per year. Paraphrasing Milton Friedman, the difficult thing about preserving freedom is that one must be willing to accept some low level of evil without doing anything legal to stop it.
