I didn't say most will, but the law of the land would change significantly and it goes back to more lawlessness. You will find there is more murders and rapes etc where there's very little going to be done about it. Obviously the threat of punishments and even the death penalty doesn't stop people from killing or committing crimes, but I would see it as going to some sort of post-apocalyptic scenario where it's everyone for themselves and you fend for your own life and family. There will be certainly less systems in place to prevent and investigate such crimes after they've happened I think.
Sadly, I think you're right about lawlessness increasing. I just like to think that it wouldn't quite be like the "Wild Wild West". I still think that most people would want to do good things. I don't know enough about libertarian ideas to talk about it in depth. I don't know what libertarians typically think about law, police, and justice. I'm sure they would be in support of having less systems like that. I'd love to hear any libertarians' perspectives on this, if their reading.
