People are misunderstanding decentralization. Sure we can talk about decentralized technology like IFPS, but we should also talk about moving away from centralized governments, banks and legal systems. Decentralization in this context means we can form our own social group, say a commune in the desert or a virtual group online that skirts the old school central organizations and sets up our own. We could conduct our buniness on the blockchain and implement our own enforcement methods. An extreme example of this might be a drug cartel conducting it's transactions on a blockchain and if you don't honor what's on the chain then you get killed.
