Congress was reluctant to levy taxes. Instead, it borrowed money by issuing bonds. It also printed money, resulting in terrible inflation. The worthlessness of Continental currency inspired the phrase, "not worth a Continental." It became more difficult to get people to lend money. By 1779 and 1780, Washington's army had to confiscate supplies in order to feed and clothe itself.
I feel like this is kind of counteracting the freedom that they were fighting for in the first place. If there's a need to confiscate supplies then it doesn't feel very freedom like.
