The question of the OP wasn’t about an idealized time when no one was tempted to do anything wrong any longer.
The OP was talking about if Chareiedim built a theocracy to enforce “Torah law”. The reality is that barring an ideal state of affairs where evreyone will WANT to keep the Torah without it being enforced such a theocracy would look more similar to the country ISIS is building then a country like the USA
Can you explain what the concept of locking someone in a “kipah” and feeding him barley until his or her stomach burst was and when it was applied? I have personally heard Rabbi Avigdor Miller say in one of his Thursday night lectures that the death penalty was not frowned upon by chazal and that when someone would get off on a technical issue they would apply this punishment to them. Also do non Jews need eidim and haasrah?
