Your perspective is very self-centered. People die when power goes out for extended periods like this. Especially if the weather is exceptionally hot or cold.
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.
