It seems this fundamental aspect is lost on people and everyone gets caught up in a flurry of arguing over who to trust. The entire point in decentralization of power is trusting any one entity (or group with aligned incentives) as little as possible.
The simple, easy, and wrong answer is to try to optimize certain groups of people with aligned incentives by removing barriers to what they want. Those barriers, if at the service of the rest of the system are the very reason the system works.
