Hmm. If bitcoin wasn't a payment network, it wouldn't work. We've already had hard money and a gold standard. Gold is not a payment network. That money (gold) was corrupted by being brought into a centralized network lacking transparency, and stamped with the authority of the state.
If bitcoin was not a payment network, nothing is different. There's no way to enforce rules. There's no decentralization. Its brilliance is that it flips the dynamic and as a decentralized payment network (as well as a hard money) with transparency, brings currency into ITS system. That currency is whatever quotes it. That's the Trojan Horse.
Fix the money fix the world is an ambiguous statement. Fix means something different than replace.
