Sometimes I wonder if the US government purposely doesn't allocate a chunk of bandwidth to a medium range digital mesh network protocol specifically to prevent losing centralized control of communications. It was only through a backdoor (LoRa) that things like Meshtastic can exist. Imagine if a protocol could be designed for it instead of having to reuse one meant for IoT sensors, it'd be incredible.
One of those incredible things only an altruistic billionaire could give to the US/world at this point. Who knows, maybe something like Wifi HaLow can fill that gap
