> If debt holders dump the 10-year bonds enough, it causes real issues for debt repayment.

No, it doesn't, it impacts future borrowing. Third time, before my blood pressure spikes: that is an argument about future debt. It being true (or not) has zero relevance to the current size of the debt. You could be right (or wrong) if we had zero outstanding debt, or if it was $70T.

Ergo, it's either an incorrect or bad faith analysis of the situation. The current debt (whatever its size happens to be in the fiction being spun) will be paid off at the bills' rates and on the statutory schedules. Period.
