Can you expand on how alternative currencies can help economically depressed communities? I can see the use case of getting money out of poorly managed fiat currencies, as with Greece or Venezuela, but I don't think Detroit's economic problems have anything to do with the dollar itself. The linked blog mentions Detroit, but doesn't go into much detail.
