What did Alexander Hamilton mean when he said the public debt "was the price of liberty."?

That even though Liberty didn't have a price tag, the debt caused by the Revolutionary War was "price" for freedom and that debt that should be repaid.

To my own interpretation, it meant we must sacrifice some part of our life for the chance to live in freedom and liberty. it was the cost we had to pay to escape England's (Great Britain's) Tierney.
