I cared for my community so you have 100 people against you. Even if you were in a SWAT police uniform because of internet trolls, while in current system I would be probably get legally murdered by such entity.
Ok. I'm current society you call police, in next 10 minutes you get to murdered. In an hour or 2 police comes and of your murderers were bad then they left evidence that makes them go to prison financed from other people taxes. You are dead.
It sucks that someone got murderer by police arresting the culprit and putting them into a publicly funded prison seems largely ideal plus or minus your view of the death penalty?
It tries to destroy incentives for these behaviors before they happen. You have to address that on case-by-case basis. A lot of acts we consider harmful stem from bad material situation, which is an inherent part of this system. System needs people in very bad situation to be willing to do the worst jobs. And anarchists overall think that you should put more action towards HELPING a person that got harmed than only punishing a persecutor of harmful act.
This is more or less the goal of every system of governance aside from strongman rule. You’ve proposed the common desireable end state with no explanation of how to get there, and then acted as if your solution is credible as a path to get there.
Governance is hard. And has problems. That doesn’t mean the opposite of governance is the answer.
As the slogan goes, "no government doesn't mean no governance." Anarchism is about a different way of doing governance where decisions are, as much as possible, made by the people directly effected by them, as close to the problem as possible. Anarchists are generally not opposed to governance, they're opposed to the particular form of governance represented by the state.
