The OP is about the dollar as the global reserve currency. The depth of the bond market gives its liquidity regardless of debt.
But I agree that your point is a serious problem.
But it all ties back to the risk presented by a currency backed by a country that is economically irresponsible and in debt that it can never recover from.

Yes, that is a long-term problem for the US.
The only saving grace is that (1) the dollar is still the global reserve currency, and (2) the other relevant nations are worse off.
