Solarpunk

While I support every word you said, I am still not convinced, that the issue can be solved completely through prevention. Even though, during the last 200 years we've made huge progress in hygiene standards and medicine, there are still people dying, even from easily preventable or treatable illnesses. In the same manner, I believe it's impossible to prevent all kind of psychopatic violence or malicious behaviour. Hence, the question that comes up would rather be: how to deal with the violence that's still occuring? Are prisons or some other kind of correction facilities a part of a solarpunk utopia?
