All communities have leaders, whales, whatever you want to call them. Even Bitcoin is now controlled by a small group of mostly Chinese people. Decentralization does nothing other than put control in the hands of an unpredictable and potentially unaccountable group of people, whereas centralized systems have people you can point to and hold accountable (or so we hope). There is a reason it's never worked throughout history, and why decentralized systems always collapse into a more efficient centralized form.
