Our system is sized for, and generates, 110% of the power our home needs, but we still have to pay for the grid tie-in. I cannot, and I doubt he could either, buy the powerwall, disconnect from the grid, and be self-sufficient. There are other solutions available that do the same, but you are still required to have that grid connection.

No, they had solar prior to Tesla selling them, so they bought the power wall separately.
Do you have a bi-directional meter? Because if so the advantage of battery is that you can reduce the amount of energy you buy at the "buy" price and sell at the "sell" price. Since those are usually quite different there is still a benefit.
I agree that its bogus you can't disconnect from the grid if you want to though - why you should be mandated to buy something you don't want or need seems silly.
