Ahh, just so I understand correctly: the premise is your currency's inherent value is backed (in someway) by debt owed? That's meta as hell if I'm reading this all right.The upside is if you have sovereign debt accounted in your currency, you print all the currency you need and poof you're out of debt.
Depends on which side of the New World Order you stand. If you're the USA, your debt is marked in dollars. Need to pay it off? Print dollars. If you're Zimbabwe, your debt is marked in dollars. Need to pay it off? You're shit outta luck. But you can pay all of your domestic responsibilities - government salaries, pensions, etc - in Zimbabwean dollars which throws your entire country into a depression. If you're somewhere in the gray area - Argentina, for example - you have a little of this and a little of that. You print Argentinian pesos and pay off everyone you can, then the people who are owed dollars whinge and bitch and demand your money and you try to say "fuck off, we're a sovereign nation, you'll take pesos" and then they sue. Not sure how they think that's going to get collected. Sanctions? See, all this shit is theoretical until it isn't.
