All existing currencies are said to be debt-based. Originally, the USD was backed by gold/silver. That gold was stolen behind the scenes. So today, there is an accounting problem at the point of creation that derives from the theft. A common language does not entirely prevent theft, but does provide accountability in the future, while also providing alternatives to money supply constraints via wealth translation.
Bonds were not originally the creation of paper USD without value. Bonds were a debt, based on collateral (gold). The USD was a receipt for such. When the gold was stolen, the Fed defaulted on that receipt in 1933 (domestically), then in 1971 (internationally). Since then, dollars are created at the time of bond purchase with only legal limitations set on their creation.
