Economy, Morality and Libertarianism III

The country increases the amount of its money with reason and fairness in mind by taking on debt when the tax revenue isn’t enough? National debt works, which proves that it was possible to increase the amount of money in the national economy beneficially?

Without taking on debt important work might have gone undone? And the currency hasn’t lost all of its value?

When the amount of money is increased this way, some amount of rewards for work need to be given up in the future to pay the debt?

Increasing the quantity of money by creating it without it being debt would require central planning, which can’t be done because we don’t live in a state of complete mutual agreement?
