No, you get paid interest because money now has less value than money in the future. Hence why you pay interest to a bank on a loan or mortgage, but if you fail to repay they don't just write it off saying "oh at least we got some interest!"
The US government gets to pay x% interest because they can theoretically always service a debt denominated in USD. Every other borrower in USD pays (x+y)%, where y amongst other things represents the risk that they will default.
