There are a lot of problems that decentralization do not solve. For instance decentralizing currency exchange systems don’t solve anything that the centralized systems haven’t already solved and solved much better.

If you launch a system that facilitates a diatributed ponzu scheme operated by thousands, then neither you nor them end up in jail.
