Exactly, and that is the problem that needs to be fixed. Paying more for the same things doesn't solve a spending problem. It makes it worse. You could completely eliminate international trade and still have a debt problem. You just slowly sell the country and economy to lenders until there is nothing left.

Edit: when you run a deficit, you trade worthless paper for real goods and services. If you don't take on debt, they have nothing to do with it but spend more and buy more goods. If you limit debt, you get negative interest rates in real terms

> Government budget deficits are part of national savings. When Washington runs a larger budget deficit, national savings goes down. In a closed economy, interest rates must go up until households save more (and consume less) and fill that gap. In an open economy, the needed savings can come from abroad instead, and as a result we end up running a larger trade deficit.

This would suggest that if we eliminate free trade, inflation will force us to manage our budget deficits.
