How far away are we from a system that just exchanges what you have for what the merchant wants? Will fiat ever be incorporated? It seems like fiat will continue to become a more evil necessity for the next decade or so and since there are so many of us trying to lock ourselves out of it we should at least keep a mechanism in place to get in and out as we need to.
