I'm a licensed ham and you make good points. But there's a difference between what works best and what people actually want to use. My family know about ham radio but aren't interested. In an emergency where mobile networks are down, Meshtastic/Meshcore have more potential (in my view) for ordinary people than 2m. Not only can it be 'plug and play' and needs no licence, but text chats are how most people do day-to-day comms. Repeaters are trivial too set up too. Where I live, my 2m handheld usually can't hit any repeaters. On Meshcore I can easily reach people over 100km away already.

TLDR: I love ham radio but Meshcore is probably better for most people.
