If that's what you were trying to say when you said "acceptable price" then maybe we agree more than I thought at first.
Put it this way. Many people are killed or injured in car crashes, and yet that is not enough to make us ban cars. For all the harm that they do, they also do a lot of good, and we've decided that the good outweighs the bad (otherwise we would just give them up).
As callous as it may sound, we have accepted that cars are worth a certain number of deaths. We still want to do everything we reasonably can to make them safer, but the safest solution (padded cells) is not worth what we'd be giving up.
