Does it though? Logically that's what we should be doing now (and it sort of is - all of those currencies are freely tradeable on the markets today), and yet we still use the dollar as the base currency for almost everything. We don't have to, but we do, because otherwise you don't have a single, comparable figure you can place on anything. I get that not having a single figure is entirely the point, but even now, I don't think of bitcoin in terms of what it costs in pounds (even though UK here), because that's not how we collectively value it for comparison's sake. I think the US would have to destroy its' economy entirely (or enter a period of genuine hyperinflation) before we move away from it as a base currency.
