One really interesting issue is how they are actually going to make the zucbux actually stable. This seems like a straightforward problem to solve: for every zucbux in circulation, stash a euro, a yen and a USD somewhere. Except ... where do you actually stash those? In what financial institution? And how do you know said custodian is risk-free? Who is going to audit them to independently guarantee that the underlying funds actually exist? As it turns out, the only entities that can somewhat securely provide that service are central banks themselves, and that means they have to be willing to play ball.
