4. A couple of your fundamental facts are not accurate.

EV batteries are designed to be replaced when they can only be recharged to 80% or less of their original maximum capacity. That is expected to take at least 10 years under normal usage - most cars only last about 8 years.

The utilities pay different prices for electricity they need for different purposes. The power from storage that can be turned on/off extremely quickly is some of the most expensive power they need. It routinely costs up to $3.00/kwh IIRC.

Google this paper, it will tell you more about the market that V2G is destined to serve:
