You sure you don't have this reversed? The average person uses the internet to watch tiktok videos and join zoom meetings, all of which is centralized. The people self hosting their NAS or minecraft server is a tiny minority.

in fact, Jitsi uses p2p with WebRTC until a third person joins the call: then migrates the call to be relayed.
A really nice latency win.
