@cjd @gargron @lain I'll argue again that blockchains haven't succeeded where you're claiming, and I believe I know that because I'm close to several people who work on blockchains.

b) the people I know who are working on blockchains are being careful to distinguish between tokens that are primarily for a "useful purpose" (eg filecoin) vs ones that are meant to be money exactly for financial oversight reasons
