You are correct. "Reputations don't require enforcement"
But the system that tracks and recognizes them does.
Enforcement from and by whom and how is certainly up for debate, but it will require enforcement nonetheless.
Not enforcement of reputation but of the rules and methods by which it is quantified and tracked.
Just need some sort of standard developed so that people can rate each other in different ways & those ratings can be weighted in some sane & helpful fashion. Lots of social graph problems to be solved in decentralized systems.
Which is why small communities are far more likely to accomplish and maintain a system that will work.
Any larger system will fail in the face of human nature.
Nah, I think, like Bitcoin & the internet in general we will see certain standards emerge that will spread & scale to facilitate the development of robust global trade networks
