US Government taxes certainly do support the US Dollar's value, but that support was more vital at the creation of the currency than it is today. Today's value is secured by the many merchants who trade in the dollar at fairly predictable prices. Iran comes to mind as a merchant who could make a similar commitment to a cryptocurrency. What if you could suddenly buy oil at BTC X per barrel? This could establish enough of a link between BTC and a high-volume commodity that it could create some stable value, and might appeal ideologically to a class of economic actors that are already somewhat motivated to avoid trade in dollars and euros.
