While I completely agree with you (and still carry blankets in my trunk in AZ!) the freeze in Texas was an anomaly that may nor may not have been reasonable to plan for:

> Texas experienced temperatures over 50 °F [28 °C] below normal. Records more than a century old were broken

How many people have planned and can execute plans for once in a century events that happen at scale?

I’d consider myself more prepared than most, but if a large chunk of Phoenix lost power in the middle of the summer for more than 24 hours, I think the result would be even worse. There was a study from a few days ago that predicted >12k deaths during a heat wave+power outage. That makes me reconsider not getting whole house batteries ;-)
