Here is the elegantly simple and obvious solution: because a nation’s government has the power to create money, do so. Instead of rolling-over the national debt as its individual securities come due and are redeemed (paying them by additional borrowing), just pay them with government created money. To avoid inflation, concurrently restrict the banking industry’s fractional reserve power to inflate this money through lending by increasing their reserve requirement proportionally. The reserve requirement is the percentage of deposits they cannot create credit from when someone asks for a loan. This ends the debt while maintaining the money supply.
