Most people do not know that communities can create their own currency to exchange for products. This process started during the private Federal Reserve caused Great Depression and is still legal today. If the State of Arizona would create a State bank, it would be much easier to produce.
There are problems with the system such as the possibility of counterfeiting. There can be a charge for exchanging the currency into private Federal Reserve notes and vice-versa. Berkshares uses 10%. They can only be valid within a certain area. I am not entirely sure of all of the rules, but it might be possible to create a Coconino County currency. Local businesses must be willing to participate and banks must be willing to provide a means of exchange and accept them, as well. In the communities with currency, the banks charge a fee and make money. As you know, money changers have never balked at the opportunity to make money.
Another problem is that when the central government decides to go to a cashless society so that it has totalitarian control over every aspect of your life, they will disallow this program.
This program could help the community in many ways and those options are at least worth exploring.
