Historically government backed currencies are are stable because they have two underlying components: an economy denominated in the currency and an implicit threat of force (e.g. standing militaries). It's one of the reasons the US dollar is the chief reserve currency around the world as well as the denomination in which oil is traded in. You need dollars not because people have faith in them but because people have faith in the underlying institutions they represent. It's fine to claim you back bitcoin because you don't have faith in the traditional institutions but pretending that those institutions don't support dollars in a way that crypto/bitcoin isn't seems a little near-sighted.
