>national debt [...] no money to go around

Let's imagine that I'm a government that reserves the right to be sole issuer of my country's currency (though for political reasons I've delegated that power to a government-sponsored enterprise whose leadership I appoint). Now let's say I also issue securities denominated in that money. From my perspective, what's the difference between money and claims on money? From a holder's perspective, what's the difference between them? Even the obvious difference, one has yield and one does not, is pretty misleading, since the interbank rate tracks the securities rate.
