So Communities If you got food you are blessed issue your own money and stop dealing with people who don't benefit you.
If you issue your own money and goverment come to buy with their money you can set your own rate higher so If they don't want then you sell to those who want.
Off course they want becouse everybody need to eat
So you make your own money and your own Community people all live Nice.
If you and the people in your community creates your own currency, that means that you have automatically created your own republic and no country will accept that. If the aim for creating your own currency is so that your community will not be under the financial control of your country, so that people who needs your crops because you are a farming community will have to buy with your community's currency, I think that there will be a problem. What if you need to buy a truck from another community that produces automobile and they are demanding payment in their own currency? So community currency can not work effectively, you community should go into mechanized farming and if your product is in high demand your community will make more money and become richer. A community can choose to accept Bitcoin as an alternative currency, it is decentralized and you can spend it anywhere without breaking out from your country.
