Well, that's all and good, but where are the rest of the people in the world... you're only considering producer/consumer pair.
This oversimplification is harmful.
The real world has intermediaries, who add value to a transaction.
Recommendation information from friends Quality enforcement information (USDA, FCC, UL, etc) Merchants who have reputations tied to the quality of their wares
All of these get thrown out of the picture in the diagram... they are 90% of any transaction... much to big to ignore.
VRM is really about re-wiring the intermediaries, and providing tools to enable them to better add value.
