If folks followed your advice the irony is that the interest rate paid by federal debt would just get higher and higher—at some point greed would overwhelm even the hardest of hard core libertarians and they would be standing in line to buy government debt.
;-)
P.S. The reason for this is that markets are ultimately cold equations of risk vs reward. If the reward gets way above the risk level investors will want in....
In the meantime, forcing a higher interest rate on government debt would increase the pressure on it to cut "spending" (really, just stealing and redistributing) and get its house in order. I really don't see an upside for non-leftists when it comes to avoiding government debt. Worst case it forces the government into default - in that case we can laugh at all the leftists who are the bagholders.
