I agree that it's a solution in search of a problem but moreover it's a technological solution for a social problem. If some federated soviets for example had a decentralized logistical software that simply naively trusted what the other soviets reported it would indeed obviously be abuseable but the idea of these groups federating is that they should have a baseline level of trust and shared goals such that cooperate. If they are incentivized to abuse the system then it has already irreparably failed on the social level.

To be clear I'm not being completely utopian here but relying on the fact that abuse of a logistical system can still be detected by other auditing means without needing a fully trustless system like blockchain.
