This line of reasoning is broadly underrated. Sure batteries are a thing, but if a liveable world means regular brown outs, I’m cool with it. The alternative after all is so much worse.
Honestly not even brownouts. I was so hyped for the potential of IOT to let distributed power management be a bigger thing. Throw your laundry in the wash when you have enough and just let the electric company trigger it when they’ve got excess or low consumption periods to help balance things.
Instead we get unsecure cameras or DDOS botfarms piggybacking “smart” thermostats or fridges that let you tweet.
Giving the electric company access to turn off my appliances is also a security issue. By all means, let me subscribe to a feed that expresses what the company would like me to do and maybe I’ll set up automations to turn stuff on and off from my end, but there’s no way in Hell I’d cede control of the switch to an entity outside the premises.
