I'm as much of a crypto skeptic as the next guy, and there are plenty of decentralization failures in crypto, but you can't have "all these centralized exchanges". The fact that there are so many suggests something worked.
I don't think the promise of Bitcoin was ever that there would be no exchanges, only that no one would be beholden to any given provider. As long as you can pick up your keys and seamlessly start trading on a different exchange, that part of the crypto world is not centralized.
