When a disaster devastates a community, and takes weeks, months ... to come back to "normal " you'd expect bater to emerge as the basic tool of post-disaster economy. Batering needs to be explored for many reasons. One : who sets the value of anything and how is agreement reached ? Is there no system for example ? Is it your need that dictate what goes thru a bater. You need a few shots of insulin, and the other guy demands a month's supply of wheat. Well ??

Also, how would you even find matches ???
I mean how do you find the folks that need what you have versus the guys who have what you need ??? Will church or Red Cross Center be a "batering market" of some sort ?
