I'm saying that under the Federal Reserve system, the total indebtedness of the U.S. economy must always increase. If the government starts to pay off its debt, the private sector must increase its debt levels. If the economy doesn't keep borrowing money, the money supply would rapidly collapse, leading to a deflationary spiral. The only money that never has to be paid back are coins. Do you have an alternate understanding of our monetary system?
