For me at least, the only thing where availability really matters is main personal communication services. If Signal was down for an hour, I'd be a little stressed. Maybe utilities like public transportation, too, but that's because I now have to do that online. > Intentional downtime lets everyone plan around it, reduces costs by not needing N layers of marginal utility which are all fragile and prone to weird failures at times you don't intend. Quite frankly, I would manage if things were run "on-supply" with solar and would just go dark at night.
