The State is hostile to privacy-coins. Its kind of astonishing that the State is not hostile to all crypto as it seeks to separate money from state. Back in the olden days, I thought bitcoin would go to zero because of how the Feds neutralized the Liberty Dollar, this flaw in my modelling probably cost me $100m :(
(Liberty Dollar founder was convicted of "making, possessing and selling his own coins" which were either silver coins or paper-notes backed by metal)
fwiw I think NFTs will be a big deal b/c they will unlock experiences. If we ever move to a Metaverse-type system, this will enable the creation of uncopyable digital experiences (can't just rip an mp3/mpeg)
