Imagine living in a village in the far past. Your neighbors with whom you will live with for 50 years form close relationships with you. They constantly judge you. They believe in nonsense superstitions, and further judge you by that. If you ever do or convey one thing that goes against their beliefs, they will kill or exile you. You do not sound like any more of a reasonable person. Contrary to popular belief, we do not live in an enlightened time. People still have the same mundane superstitions and morals and actively seek to punish people for violating them. I do not want a village future with you. CCTV is a means of enforcing the will of the people, and only the most opinionated people. It's not worth it for whatever small benefit like a few crimes being solved or punished.
If you can catch offenders everything else is just a matter of adjusting punishments to sufficient severity that offenders are removed from the system faster than they manifest.
