This entire fiasco is stupid.
Treasury bonds/bills are just “future dollars”, while physical cash and electronic deposits are just “today dollars”. The idea that a sovereign government can somehow default on obligations denominated in the currency it creates and controls is absurd. It can no more default on treasury bills than it can default on dollars, or accounts at Fed - either can be created at will, physically via printing press/mint OR electronically via crediting an account at the fed.
The “debt outstanding” is just the number of dollars the government has created. But the way we calculate this number doesn’t include ”today dollars” the government has printed, only “future dollars”, so it seems quite meaningless to fixate on it.
And it is not per se irresponsible for this number to be high. It only becomes irresponsible if there are negative effects on the broader economy, primarily via inflation but also other effects like crowding out private investment and reducing growth.
Right now we are in an overly inflationary environment right now, and the government should be printing fewer dollars (“austerity”) via lower spending, higher taxes. It would be reasonable to insist on changes to spending/taxation policy.
It is irresponsible to take money (today or future-dated) and imply the government may no longer honor it as money. You are destroying the public’s faith in money, and losing the ability to buy goods and services with it. This is why many countries can’t get others to accept their money as payment, and have to issue bonds in a currency they DON’T control. This is not a good situation to be in.
People take the intuition that it is irresponsible for a household to have too much debt because it might not be able to repay it, and apply that to the government which can create those dollars. It is not the same.
It is like saying Starbucks can default on “Starbucks points” that it owes to people. So long as Starbucks exists, it can hand out however many Starbucks Points it likes, because it decides what a Starbucks point is and maintains the records of who has how many points. There might be Starbucks Points inflation if they hand out too many, but it is always possible for them to meet Starbucks Point obligations.
