a. Yes, but you can easily put up solar+batteries such that the cost of retail energy to the consumer is entirely transmission line rental, at which point disruption is worth whatever the cost of line rental is minus the capital cost of grid construction.

> It’s possible to sell power to the utility for a reasonable price per MWh. But one can’t easily sell to the utility’s customers.

You might not be able to sell energy directly to them, but you can sell/lease energy generation to them which is essentially the same thing. You won't be able to charge the line rental that makes up the majority of the retail cost post installation of solar, but you can start with some fraction of the difference between they save with the solar system, which is probably at a better price point than wholesale cost of electricity.
