Makes sense. And my cohort comes from an era when we can talk to anyone, anywhere, but the channels are controlled and watched. The ability to communicate isn't special anymore, but the ability to communicate independently and privately is. We don't want communication, we want known-good (dare I say, safe?) communication channels.
Do you think that ham radio couldn't be? Or isn't? What you really want is privacy, authz/authn concerns, and decentralization, it sounds like. And TCP/IP is about as useful as a "PHY" layer for your application as is ham radio.
Plus, solutions like what you're describing require a relative ease of use - unless you only want to talk to the 17 other people in your geographical area who have similar technical backgrounds.
And that's just the beginning, before people put in the effort to make it more accessible.
TCP/IP isn't the point, it's the encryption that lets me send encrypted, secure emails to my friends over a network that only wideband jamming or a natural disaster can take down.
We could have a leaderless IRC server, leaderless peer discovery and routing, IP/DNS controlled by consensus.
