It is unfortunately not such a simple matter to pay off the national debt. The dollar is a debt currency.
Investopedia has a good write-up on reserve ratios and money multiplier here: https://www.investopedia.com/terms/r/reserveratio.asp
Paying off our debt would destroy the dollar with a massive deflation.
When a loan is issued, "money" is created out of thin air. Suppose a bank has 500M USD in deposits, and the reserve requirement 10% - the can make 450M USD worth of loans, which all turn back into deposits at some point. With that extra 450M USD in deposits, it can lend another 405M. When that 405 comes back in as deposits, the bank can lend another 364.5M USD, and so on. When the loan is repaid, the money created by the loan is destroyed (a little at a time as the debtor meets his monthly obligation to the bank).
The USG is 33T USD in debt to the federal reserve. If it is repaid, that's a lot of money that'll just evaporate.
All of that leaves us really with a Hobson's choice. It's why our founders were absolutely against currency and actually wrote into our constitution in Article I Section 8 that the federal government would have the power to "coin money." It didn't give it the power to "print paper."
I hope you realize I wasn't actually advocating for paying down the national debt but was instead trying to illustrate that the bulk of the spending down by the U.S. (and therefore the most likely places to cut spending) are social entitlement programs.
I'm definitely not an expert, but I'm versed enough in money supply (M1, M2, etc.) and the treasury markets to understand the dilemma we (and much of the world with exposure to international markets) face with devaluation when sovereign debts are fully repaid. Makes it hard to shrink the balance sheet.
