I think a solution to this is mandate providers provide a cellular interface for households for emergency response, with battery backup. Basically a mobile hotspot with a phone jack, speaker, microphone, and red button to call for help attached to a chonky batter pack. Device inventory and health is required to be reported to regulators.

This solves for power, and reporting means it’s trivial to log and audit if the devices are online and available for emergency service calls.

If a mobile tower isn’t available in the area, a tower must be made available for the sector coverage.

Anything else in a world of fiber to the home is compliance theater, as your example shows.
