If a large majority of us learned how to meet our needs sustainably and directly, the corporations would either shape up or go away due to not being needed. Once the governments and corporations went away, so would most of the useless subhumans that are dependent upon them, along with most of the psychopaths because cheating man made systems is how they've risen to the top.
You're right that most humans these days need government but those humans and their lifestyles are going to kill everything if something doesn't stop them. I think it's time for those that don't have the intelligence or empathy to find ways to exist ethically to go. Crashing the slavery systems they're dependent upon will cause quite a bit of them to self eliminate. If humanity wants to survive, the civi slaves must go.
