I'm not in favor of regulations in general. But this is a reasonable one. You never know when you'll need the radio. Just look at the fires in Lahaina last year.
When I lived in Guam the government recommended, not required, that everyone have an emergency closet in case of a major typhoon or earthquake.
The recommendations were at least, three days of canned/dried food. 40 pounds Charcoal or 40 pounds propane, whatever your grill used. Five days of bottled water. Flashlights, Candles. Matches. At least 1/2 a tank of gasoline in your car. Batteries or power banks for a cell phone, and a battery-powered AM/FM/Shortwave radio with extra batteries.
When the power went out you needed that radio to hear government warnings and announcements. The internet and cellphones were down; the radio worked.
