I think that by eliminating the need for a merchant to learn information about your identity I have aimed higher. Given that we're talking about credit instruments, however, it may be difficult to eliminate the need for the issuer to track transactions. However, given the way I've described the protocol, it would be possible to use a variant on it for digital cash purses without the merchant being impacted. It isn't clear to me, though, who would issue such things in the current environment.
