> No provision of these rules prevents the use by an amateur station of any means of radiocommunication at its disposal to provide essential communication needs in connection with the immediate safety of human life and immediate protection of property when normal communication systems are not available.
That rule applies only to amateur stations (it says so right in the text!), not unlicenced individuals. What an amateur station is is defined in the beggining of the document, and yes, that requires the a duly-authroized (licenced) operator.
The last thing you want in an emergency event is some prepper with a baofeng transmitting on a repeaters frequency without a subtone set (because he's too stupid to pass an exam that 10yo kids can pass) effectively jamming it for proper emergency users. The other thing is, that chances are no one will actually hear you, especially on simplex. With tools like garmin inreach, carrying an HT with you instead of something proper and relying on that to save you in a time of need is just stupid.
Ham radio is like driving, you need experience to do it, and even some experienced people still do it badly. Trying to figure out how to drive by reading a car manual while the flood waters are rising is going to be a pretty bad experience.
Ham radios don't just appear, someone has to buy them, buying one without getting a proper licence is just stupid.... but many (especially americans) do so. There is GMRS, there is FRS, people could take those radios, try them out when not in an emergency, but nope... everyone wants that uv-5r for some reason.
Every one of those preppers should get licenced first, go to some hiking trail, some remote..ish pota park and try to do an unspotter POTA activation there... and after failing horribly, they'll rethink their emergency communications. Somehow even licenced hams (about which I assume none actually tried doing an unspotted pota from some hiking trail) support and spread the "just buy a baofeng for emergencies". In reality... they're useless in most cases. If you're somewhere remote, no one will hear you anyway, and if you're stuck at home, having something like a starlink will actually help you reach someone, much better than a radio, especially a handheld 2m/70cm one. You might get some good but useless DX with an HF one, but you won't be setting up an NVIS antenna in a snow storm.
But hey... try explaining that to preppers.
