A lot of our city uses bitcoin already. We have bitcoin machines here too. The point would be a local economy mostly. Although nobody could really stop others from trading it or accepting it elsewhere, the goal would be using it here. MIT has a digital currency just for MIT students. Same deal except for a small city.
