The technology is just too distributed already for any of that to happen.

Cost of charging an EV is bounded by the ability to add solar panels to your house (currently solar installations “pay for themselves” in 7 years in Seattle - not so sunny - high cost of labor location). The grid and “free market” have to be able to compete with that for cost.

Batteries like solar panels are very cheap to transport. They are flat, they can easily stack, there is no expiration period, and no temperature regulation needed to transport them. Batteries will be produced globally if the local markets start gouging.

Solar panels are already a great example of this cost reduction curve. So I’d say your outlook is very pessimistic and not backed by the data.
