"Decentralized" doesn't mean crippled. "On-chain" does. At some point, you need to interact with the off-chain world (say, when you want US dollars and not tokenized US dollars), and that path to the physical world becomes a point of failure that can be controlled by mundane means such as uniformed people with guns. The crypto-utopian solution is to move everything on-chain. The pragmatist solution is centralized exchanges that more-or-less plays by the rules of wider society and is allowed by society to move stuff in and out of the blockchain.
