I agree with what you are saying, but even before that point, the USG which is sovereign over its money supply, will be able cover any liabilities it has by creating the necessary money. This is what I was alluding to when I mentioned that the USG won’t let itself go bankrupt. They will destroy the USD before going bankrupt, because the repercussions of going bankrupt are much worse than a lower valued USD. Also, the whole debt ceiling is a charade; the FED can and has monetized treasury debt without any fuss.
