I think the only reason why the Nordic countries like sweden could eliminate fiat money is due to the fact that they are very social democratic countries, and have almost none poverty rates. But could you imagine eliminating cash in the US? How would the droves of homeless and impoverished people pay for anything? They certainly can't get credit cards or debit carbs, because they either don't qualify or can't afford the fees. There has to be a very very stable socioeconomic environment for the elimination of cash, 100%.
