You can buy a used Leaf with twice the capacity of a power wall for 1/3rd the price. Then a $150 inverter connected to the 12v system to power the lights and refrigerator in your house and you have emergency power for a week. Plus you can take it to the grocery store or anywhere else local for the other 99.9% of the time that the grid is up.
And you can charge it from solar power at home when the grid is down. This is a much more economical approach to backup power than a huge investment in a PowerWall that you only use 0.1% of the time. IMHO...

Oops, > this would kill sales of their powerwall. > I would love to have a powerwall (or two) which would give me 14-27 kWh of backup power for the house in a post- hurricane situation. Then I would ALSO love to plug a car in to get an extra 80-100 kWh of extra backup power. So I don't think V2G will necessarily remove the need for the powerwall. You will definitely still need the auto-transfer switch to use V2G in a backup situation... and it would be nice to go someplace in your car (perhaps to a nearby supercharger that does have power?) while keeping your house powered with the powerwall. So I think it is very complementary to the powerwall.
