I really don’t mean to be harsh, and this author cited sources, but apparently neither they nor the author really know anything about how money actually gets created in the U.S. The central bank cannot unilaterally create new money without the participation of the treasury of the central government. It simply isn't allowed to do that. There is never a time when the central bank has "no savings." Also, buying existing bonds does not add to debt — though it can add to the supply of money (as currency) for the economy: that is called ‘quantitative easing’ (QE).

Yet, it is true that all money in this nation is created via debt. I have developed an alternative monetary paradigm that would provide the supply of money (as currency) for the economy without involving debt: "Re-thinking the Economy's 'Fuel System’ to Avert the collapse of Civilization" (here in Medium).
