MMT proponent arguing against paying off the debt: “but then you wouldn’t be able to buy any US Treasuries, and what would the world do without a risk free interest bearing investment?”

They lack any ability to imagine a world outside of currency/economy manipulation. We wouldn’t need a risk free rate in that world, currency itself would provide a real return as the economy became more productive. Fixed unit currencies are in same ways interest bearing.

Todays currencies will never be fixed. #bitcoin fixes this.
