Don't ignore the very real human cost this would bring. Every day the power is out, more vulnerable people would be harmed(including death) directly from not having electricity for essentials or from systemic failures like in food distribution and storage. Financial systems being down could also have extreme impacts on some people, but maybe easier to mitigate via human compassion.

Maybe the long term changes such blackouts would cause would be "worth it" in a utilitarian sense, but let's not hope for such damage.
