There's no natural law saying that budgets have to be balanced. Most countries run constant deficits.

Are you serious about this?

Governments being able to borrow money (to run that deficit) relies on people believing that they will be paid back. The more the debt grows, the less likely people are to believe they’ll get paid back.

The other option is endlessly printing money, which causes hyperinflation and you get an Argentina/Turkey/Weimar Republic situation.
