for me, we should not fear a world without money. because, when there is no money. the way we see items is equal. Example: trading , when we are trading. what we want is what we get.
I agree, before money was used by many, there is this thing called barter change, they trade not money but things they have, they agree on something they have to trade with others. If they need something , they will just announce it to the people and other people will offer them something they have, they will both agree to trade to what they have.
