The web is peer to peer if everyone just runs a static webserver. Back when Opera was still Opera they integrated a webserver into the browser (with a naming system/proxy through Opera). If this would've taken off the human (but not the commercial) web would be a very different place. It still can be.

I host a static nginx webserver from home and just use a text editor to look at my log of POSTS to participate in p2p web techs like indieweb's webmention.
