I wonder if it wouldn’t be easier and more robust to disconnect homes with power walls from the grid during peak demand. Adding 50k additional active elements

I wonder if it wouldn’t be easier and more robust to disconnect homes with power walls from the grid during peak demand. Adding 50k additional active elements to the grid makes me worry about edge cases like well-coordinated software bugs or cyberattack. If we didn’t arbitrage electricity and charged real time cost, we might be able to realize far simpler solutions to our demand response issues throughout. Heavy industry already does variable rates. I don’t understand why residential and commercial customers are expected to be isolated from reality. You always pay for it in the end - usually more than if you just paid up front.
