In “Why Warren and Sanders Object to Crypto Rules” (op-ed, Aug. 24), Brian Brooks and Charles Calomiris correctly acknowledge that crypto developers are trying to build a financial system in which users have more control. But then they advocate a government-controlled financial system, much as Sens. Elizabeth Warren and Bernie Sanders have done. The difference is that this time it would be run by the Office of the Comptroller of the Currency instead of the Postal Service or Federal Reserve.
Regulators must remember that our bank regulatory framework isn’t a universal solution. Not all crypto companies should be classified as banks. Not all crypto users need banks to send money. And not all crypto users want to do business with banks. People want more financial options because they don’t like the current ones. That’s why crypto was invented.
