So, we're going to try to stabilize our currency by tying it to every failing currency across the world? If bitcoin gets mainly used as a replacement for hyper-inflationary currencies, then it's never going to be a viable alternative to an even marginally strong currency. Tying all the world's currencies together isn't going to create a stronger currency than, e.g., the dollar or the euro. Thus, those who work in dollars or euros have economic reasons not to use bitcoins.
