Are you seriously arguing that what the federal government is going into debt to do is "good debt" rather than "bad debt"? They're going (further) into debt to fund continuing operations, not just for infrastructure investments. Also, there may be some good (convincing) MMT textbooks out there. There are also a much larger number of good non-MMT textbooks out there. Why should we believe the MMT ones rather than the more-generally-accepted non-MMT ones? "This opinion exists and has been clearly explained" does not imply we should either believe it or put it into practice.
