You're making very aggressive assumptions about amount of use the EV battery would be subject to, to the point of this being a straw man. You're right that people wouldn't agree to have their expensive EV battery trashed by multiple 0-100% discharge cycles daily. You wouldn't get any takers if that was your offer. A more reasonable expectation is that people would lease a portion of their capacity. Say 20% for argument sake. You could even place other limits on it "never below 50% and above 90% on weekdays". In this example the power company gets to use between 50% and 90% state of charge in your battery on weekdays and pays you a small fee or other compensation in return.
