Actually, that's not quite how the expiration works. When it expires, it turns into regular old US Dollars, which are even better! But, if you have GD or regular USD, when given the choice, would you rather spend something that's already a dollar now or something that might turn into a dollar after some number of days? You'd probably keep your dollar and spend the thing that isn't yet a "normal" dollar. I do have a rough whitepaper written up (I've since renamed it Greshm Dollar).
