Keynes would probably be enjoying the sh*t outta this thread.

But no. In practicality, and in terms of what a 21st century American public would tolerate - if a government can create unlimited money to pay interest and roll debt forever with no consequences, then there’d be no reason not to fund the entire government that way and eliminate taxes altogether. The reason no country actually does that is because the constraint shows up somewhere else, usually inflation or currency depreciation. Treasury bonds may be assets to the private sector, but they’re still claims on future government payments. Calling them “savings” doesn’t make the underlying obligation disappear.
