The US's monetary base is $3.8T. Total outstanding public debt is $17.5T.[1][2]
If the US government were to print $17.5T in cash to cover their liability, it's not even a question that it would hurt every American with exposure to the value of the dollar. Debt is debt, and it has to be paid in the future. Every trillion borrowed today is not only a trillion we will not be able to borrow in the future, but also a trillion*exp(rt) that we will have to put towards paying debt back, rather than spending on our future needs. Printing money may sound like it's some meaningless and magical action, but it's not. Printing takes the money from people who have cash exposure. Taxing takes money from people more directly. Stealing from other countries via war takes the money from another source. But it has to be paid back in some way, Debt is debt, despite how much politicians make you want to believe otherwise so they can spend your future now.
