Money and information have lot of similarity in their behavior. They form a network a their own and hold value in only the network. Though this can be said for many things in life, it is more relevant with money and information. Both have immense value in the current world. And perhaps these two are the only two network that people are interested in participating.
It is difficult to define where and how they are generated.
Both have value only when they are used and only within their network. Imagine a group of people struck in a remote island (won’t be difficult if you watch Lost), money won’t have any use there for obvious reasons. Similarly on the same island a “not so smart” house wife will be much more useful than the programming skills of a software engineer.
