Safety is not vague. You quantify difference before and after to determine if they are safer or not, same as if you end up with more or less money.
We can't make a market do anything. But we can at least not do stupid things tasking a private enterprise which has a duty to make profits for investors to be in charge of things which lose money if done correctly. The purpose of fines is to discourage bad behavior -- if fewer people do the bad behavior then that leads to lower income. Any profit motive for collecting fines leads to the opposite of the desired outcome.
