I wonder exactly what he means by "the clock is ticking" maybe he is pointing at the inevitability of a CBDC becoming the ultimate medium of exchange in the future in every country? Something like that? I'm not sure what else he would be speaking to, but I would certainly agree that this needs to be implemented. Privacy is key, why else would USD say "this is legal tender for all debts public and private" If cash now is anonymous in physical form then BTC should also be anonymous at the digital level if it will ever be the primary "medium of exchange" or world reserve currency used by the entire globe.
