I do Aether (P2P Reddit~ish, https://getaether.net https://getaether.net) and I investigated doing something like this over radio mesh networks. Specifically doing it over HAM radio was one of the possibilities. The plan was something like doing anycast over Radio. Turns out, even those bands do have a lot of limitations. For example you cannot use any encryption, which makes most of the modern tools out of the picture because TLS is impossible. There are some workarounds like doing TLS with blank keys, but far as I understand it is dicey so far as legality goes. (The data on Aether is public, but we use encryption tools for authentication of messages.)
