translation: study shows majority of US consumers doesnt know how fiat really works.
Doh! Where do dollars come from? I think less than 10% is in tangible notes. The plastic cards are capable of reproducing pseudo-dollars or something and then there is fractional reserve banking, oh the humanity!
Not using tangible notes and instead using credit cards, bank transfers and checks only reduce the cost of spending money. Cash fiat is very expensive to move (it is very heavy and the trucks that you move it in are heavy and expensive). The sorting and counting of cash is also time consuming (and thus expensive).
