Try reading a book and you'll get those answers explained in full. I'm not gonna sit here and paraphrase volumes of anarchist theory just so you can play judge nitpicking the specifics. I have explained my position well enough. If you want specifics, go read the source materials.
Kropotkin, Graeber, Bakunin, Proudhon, Luxembourg, Parsons, etc ... All have explained the mechanisms of decentralized resistance and horizontally structured systems of authority as well as the incentive structures of how people decide what to labor on and organize with their communities to ensure desired services are rendered alongside how this change of incentives and authoritative structure would counteract reactionary efforts.
FYI, that quote is from renowned anthropologist, David Graeber, who wrote multiple books on these very subjects. You should try reading them. You'll learn something.
