Not everything needs to be peer-to-peer.

Not all things are actually viable to do in peer-to-peer. For example, peer-to-peer systems have a problem reliably saving state, therefore most of them are by necessity stateless - or terribly slow like blockchain (which is, again, okay for _some_ applications).

That's why client-server architecture exists - it provides a missing piece.

The question is - who controls the servers, and if you can meaningfully take part in its governance - or viably secede and incorporate your own server.
