What do you even mean when you say: "See welfare." Welfare is designed to temporarily give out free stuff, it's not easy, but it also is less annoying than the Police.
With the police, the entire process for reporting many of these issues revolves around convincing them to do their job. Or rather, convincing them that your problem is important enough, or else an easy enough case to make, that they should devote time to it rather than other crimes in the area.
And then you say "Going to the police is confrontation by proxy"? That sentence, at least in any civilized part of the world, is complete nonsense. The reason why we have police, ideally, is to reduce the number of confrontations by making the cost of both crime and of escalating violence swift and clear. The job of courts and the police is to prevent vigilantism, as well as to protect people. It does more to prevent additional violence both because most criminals (who aren't the best in society) know that you don't try and take on the police and because it keeps the people being hurt by crime from lashing out and escalating.
And then you go on this victim blaming "you must train on self defense" nonsense? If you live in a war zone, or a really rough neighborhood and you can't count on the police, you might have a point. But for most people crime happens rarely, and nearly all of the time there's no way to prepare for it unless that's all you do with your time. Maybe that's how you want to live, but for me and most other people, that's alot of mental and emotional energy to spend on something that isn't likely to happen.
