The same criticism applies, a global distributed consensus is fundamentally flawed as a payment system, and the current ad-hoc organically grown mess of different centralised payment systems interoperating is somehow still more suited to processing payments quickly and reliably than ‘crypto’.

Fast transfers, trusted partners, regulation, audits, identity verification, fraud prevention, backing, sound money. All these things are important and valuable, and while our current system is really flawed in some ways (in particular the control of politicians over money supply and the monetisation of debt), cryptocurrencies do not offer a solution to the most pressing problems and introduce too many of their own.
