Before we talk about the social impacts of shutting off electrical service, maybe we should talk about the social impacts of two million acres of forest fires, over a hundred dead, and tens of thousands of people evacuated from their homes?
That's a very forced comparison. If you took that seriously yourself, you had to weight having a driver's license against the thousands of people run over by cars each year, because by your logic consequences of a bad case are inherent to all the cases!
The social impact is about the cost of doing it properly or not. Not doing it in a way that causes fires, that is something else.
