If you like freedom from the Torah then obviously you wouldn’t want to have to follow it. We wouldn’t kill anyone until after Moshiach comes, at which point Emuna won’t be a sticky issue. It would be very clear.
What we have now is far from utopia. Teenagers that aren’t responsible enough to think ahead in life and weigh the outcome of their stupidity have the run of the day. Shallow people dictate to the rest of us what is right and what is wrong.
The picture you gave doesn’t square with any depiction given by Chazal. And yes, although you don’t like tickets you agree that you do want police presence. Similarly, nothing is more peaceful than a Torah run society. Punishments, however rare and almost impossible, are announced to keep it going.
