Yserbius: government has no need to regulate safety for things that are common sense? I pashut don’t get that reasoning.
First, American libertarian thought is that government should not regulate something that only hurts themselves.
2nd, this may depend on how well society follows common sense and level of intrusion required to regulate. Why not, for example, have government sponsored/required physical training as Nazis and Soviets had to ensure that men are ready for the Army? With government-subsidized helathcare, this may become an item.
3rd, carrots and tricks seem to be working in modern society better than sticks. Signing up employees automatically for 401k with an option to switch it off works way better than giving people an option to enroll.
An example where intrusion prevents good regulation in Gemora: when there are several farmers along the river, we let the first one to take as much water as he wants instead of putting an inspector. L’derech shalom. (some could argue opposite: that shalom requires dividing everything equitable )
