I have a hard time believing this. There's simply not enough lithium in the world to support every house having its own battery, let alone support all of the EVs coming into production.

Besides, there's genuine benefit being hooked up to the grid. I'll gladly pay the $10/month interconnection fee just to have that as a backup to my battery.

There is plenty of lithium. Reserves are low because until recently demand was low and so no one bothered to go and look for more. And then there is virtually unlimited lithium in the ocean, which costs more to get, but would still be a small part of battery costs.

The bigger problem is cobalt,but from what I understand people are working on various alternatives.
