For point c this is completely untrue; you in fact can’t get a payday loan without a bank account, and many of the most sleazy practices of payday lenders (and all of the practices banned by the rule) are related to charging fees against bank accounts.

A and b are both true but don’t seem especially relevant; payments can still be made on a daily or hourly basis based on the work they are doing rather than bundled up at the end of a pay cycle.
