I've been chastised for answering questions to others, but I guess I'll take another chance.
Also, that's several questions.
Do individuals trespass? Yes.
Do they cheat, steal, lie, etc.? Yes.
How is justice enforced? By just people. The key here is that the only purpose of government (ever) is to create the illusion of legitimacy for people to do evil. If something is not immoral for any regular person to do, if there is moral justification for justice to be carried out, then it does not take someone with a badge and a parchment signed by their friends to carry out justice. Any ordinary just person (or group of people) can do it.
But the real point is that no badge or parchment can give legitimacy to immoral acts. And that is what a badge and a constitution are for.
How are wrongs made right? When wrongs can be made right, they are made right by those who have the moral courage to make them right. Again, there is no need for government to do this. And if you think carefully about the wrongs that are made right in our society, government is not contributing to that process. That is not what government does. It is not its purpose.
I don't think that all wrongs can be made right, but to the extent that a wrong can be made right, it can only be made right on the basis of ordinary people acting with moral justification---usually in the face of authority/government.
I like anarchy. It is the only recognizable source of beneficial interactions between men. IMO, limited government is a contradiction in terms, and constitutional government represents a state of instability and transition from the principle of tyranny to the complete realization of tyranny. It is true that the default in human experience is tyranny, and people love it and try to justify it on the basis of order and such things. That doesn't make it practical. It just makes it continue.
