I would say this is a more accurate analogy for a pure P2P network like BitTorrent, Bitcoin, or the Pear stack (Keet, Holepunch, Holesail, etc).

A better analogy for #Nostr might be that anyone can setup a small tower and be a broadcaster, and everyone connects to any number of towers that they want (infinite range). So rather than having central points of transmission, it looks something more like pirate radio. Anyone can setup a broadcast and people can openly connect to them to communicate with anyone on those towers. So still sort of like the central point model, except it’s an open protocol and tons of people can make these “central points,” thus drastically lowering the risk that any particular tower becomes a censor, or manipulative.

In other words, rather than eliminating the central server and client model, it distributes the job of the server across tons of different relays using an open protocol and anyone can easily be one.
