She literally uses the framing of multiple Austrian theories, explains them, and then discusses why fiat money actually exists for periods despite it seeming to violate some of those principles. And then develops a sort of unified theory. Arguing why the Austrian theory is right, but it’s the resulting characteristics, not the goods themselves, that make it a good money, and thus why fiat that isn’t horribly abused will work.

I think she’s completely right and have argued as such before her book on my show using numerous Austrian writers as the basis for making the claim.
