All they have to do is change the way the current basic income system works. Right now basic income is granted to any corporate bank with charter. They are free to create M0 money out of thin air as debt on their balance sheets to loan out money that they don't have (fractional reserve). There are about 4500 commercial banks in the USA. If California simply assumed this role of money creation within the state it'd have more than enough to distribute for a universal basic income instead of the normal centralized basic income to corporations that then filters out according to their whims.
