Actually poor people deserve justice and security too?
Unless you're the richest person in the world. Because if you aren't, someone is going to outbid you on the security forces, and then it's their decision, not "the market's" decision.
Then if you are not rich you cannot even call the police because you cannot afford it. It's better to abolish police and not jail people for self-defense.
Sure, that works for some cases, but what if the crime already happened? For example, what if your house was broken into and your stuff was taken?
In that case, would your only recourse be to hire a private investigator to identify the culprit, and then personally show up at their house to exact your revenge? That doesn’t seem sustainable.
You can look for info and help in your local community for example. You don't need to extract revenge necessarily, if you find that person you can organize with some people and visit them to take your stuff back.
