I think hashcash ment as in if you have nowhere or no seeds to grow food, say you choose to live in a city (what will be in the future mega city \ smart city.. go to the v-chain website, that's most likely a city in the next decade :) ) Then if money gone, there would be food tokens , feeding the masses. People with financial freedom ie the rich, would most likely of course still be eating Organic food whilst the food-tokens are just for GM and horrible nasty "food" ??
