ps circular economies in the 21st century are a bit wishful imho, and based on 'thought exercises' that don't conform to reality outside highly remote, deprived communities. the vast majority of the world is just too interconnected nowadays - the value loops are far bigger than we realise, and basically impossible for a neo-currency to capture without some sort of top down (eg town mayor, county municipality, regional government) involvement, and even then, most fizzle and die

(checkout Tumin in Mexico - it's another, non digital, well-supported and good-hearted attempt at this kind of programme that has, like other similar projects - digital and non digital - withered on the vine)

people just want dollars/national currency and credit. 

and more people to spend money on their products/services.

well-intentioned as we are, bitcoin doesn't fix this. at least not yet.
