Clearly, you do not understand what a localized economy is. I live in a small town / village where trade amongst local businesses is valued and promoted.
The locals at the farmers market grow their own produce and....believe it or not....they eat food. I'm not talking about a sophisticated supply chain or a complex economy here. Many trade, or even barter, amongst themselves.
From little things, big things grow.
I'm not sure why you are even here on HIVE if you have this view. Why are you wasting your time? Or wasting mine for that matter?
