I realize that. It's sort of like "Disney Dollars". But I'm referring to a system that just uses Federal Reserve Notes, so that a special scrip is not needed.
It's easier to get involved in, and is more loose-knit.
So what is the point? To get people to pledge to exchange a minimum amount of goods and services within the group? That might work in a small, rural, distant community. But where people have a work product that is not a tangible need for the others, it becomes a little trickier.
