  If you used something like ipfs, syncthing, or generic 
  torrents you could easily distribute anything you want at 
  large scale at no cost, as long as people were interested 
  in having it.

The problem there of course is the "as long as people were interested in having it" part. You can publish stuff for free on Freenet, but to a first approximation, nobody actually uses Freenet. If a torrent/magnet URI runs out of seeds then it dies forever, unless you have a way to contact former seeds and beg them to give you a copy, etc etc. Bandwidth costs money, and always will. Distributing files costs money, and always will.

The UX of peer-to-peer file sharing will always be more complex than "go to this WWW URL" if just to avoid the free-rider/spam problem.
