It doesn't, it just leaves the general public holding sacks of worthless paper money or pointless numbers in a bank's database when they want actual stuff, like food
You are talking about hyperinflation, but how does that result from borrowing money denominated in dollars?
Germany's problem in 1923 was that it had a huge war debt and reparations. The reparations had to be paid in gold. But the other war debt was money borrowed in marks. So they printed money to pay back the debt denominated in marks and then created a new currency. This was not a side-effect of debt, it was a deliberate policy to erase part of the war debt and virtually any other debt held in marks by anyone. So they had a year of hyper-inflation and then went back to normal.
I don't see anything that would force the US government to adopt that strategy.
The US had the advantage of pushing a lot of the inflation tax onto the rest of the world
But the dollar was getting stronger, not weaker, against other world currencies. Causing things in those countries to cost more in dollars, but things they sold here to cost less.
Again, what does that have to do with the federal debt?
The real issue is what are we spending the money on. There is nothing wrong with borrowing money to pay for things now that have lasting future value. In fact, leveraging debt is a way to make (or lose) a lot of money. Which it is depends on the value of whatever the borrowing paid for.
