It's called torrent protocol and it doesn't work, no one wants to spend money and bandwidth hosting a god forsaken movie or book that only a handful of people care about.

(just an example, as it's way overkill for the task)
With copyright, as individuals we get to trade all of the wonderful stuff already made (and long paid for) for the flood of minute-old shit and sludge inundating us online constantly. It's a bad trade. Maybe copyright should stop encouraging creativity; the answer to how "artists" would get paid post-copyright might be "who cares, quit if you want."
We already have Herman's Head, we don't need any more crap.
What does this have to do with copyright? People post sludge online even in chaotic meme environments where copyright is irrelevant and people constantly take and repost each others' stuff.
That being said, please do not host content this way. P2P blows away the already thin privacy guarantees that the web provides. Anyone seeding the site gets the IP addresses of everyone on that site, and can trivially correlate that with other sites to build detailed dossiers on, if not individual people, at least households[0] of people. After all, that's how the MAFIAA[1] sent your ISP DMCA scare letters back in the 2000s P2P wars.
[0] IPv4 CGNAT would frustrate this level of tracking, but IPv6 is still subnet per subscriber. Note that you can't use individual v6 addresses because we realized very early on that the whole "put the MAC in the lower 64 bits of the address" thing was also a privacy nightmare, so IPv6 hosts rotate addresses every hour or so.

Isn't that exactly what WebTorrent is?
I would have absolutely no trouble downloading the latest marvel movie but if you are looking for some old Soviet movie, Iranian movie or even old American movie then you're in bad luck. I've never seen more than 0 seeder on thepiratebay.
