This is an informed comment by libertate and deserves more upvotes. However the demon clowns can just decouple sovereign debt from market rates by having the fed 'buy up' as many US treasuries as it wants. This of course means any market investor no-longer buys US treasuries but again that's just another digit they add on the Federal Reserve computers. This leaves current holders of US debt f*cked, which they might even see as a win. They have been floating essentially this tactic under the name MMT (Modern Monetary Theory).
