Well, then you haven't witnessed the beauty of What.cd or PTP. A bunch of data hoarders with webseeds. Find that rare promo release from 1978 on Vinyl? Check. Get a lossless copy of a professionally digitized Laserdisc release of a film? Check.
For now. But to survive generations you need a continual supply of new people interested in becoming data hoarders and seeding stuff they have absolutely never watched.
Which may happen for awhile, even a century. But it won't last thousands of years, unless storage space becomes infinitely big and cheap.
