I think you misunderstood. I had electricity just fine during the storm due to the wonders of working infrastructure and thus not being in a blackout.

But, for those without power due to a blackout, you can’t simply spend money and instantly turn the lights back on. You can either have already spent money to have backup power, or you have a problem. It’s like breathing, if your drowning spending money to be able to breath in 2 hours is useless you need air now.

Which is why electric grid operators need infrastructure not money to avoid causing blackouts.
