That is kind of a scary article. I tend to dislike crypto arguments that make it political. There are pure economic arguments against it, from free market laissez-faire Friedmanian perspective, from centrist perspective and more obviously from the left wing perspective, that show crypto as dangerous for society. No need to make it another wedge issue (I tried to be somewhat politically neutral here: https://benoitessiambre.com/specter.html ).

This article makes a fairly strong case that authoritarian politics could readily mix with the economics feeding on each other in an unstoppable vicious circle that eventually leads to financial and societal cataclysm.
