The parent stated their experience (one day without power) and the willingness to pay more for a specific change, they didn't say anything about longer time frames. If a single day of power outage will cause a person to die, such as those with certain medical issues, you must make preparations for backup power. I hope you can agree at the extreme that treating the entire power grid as if it were a hospital's internal power network would be absurd.
