In demand content always has plenty of seeders. The stuff that dies is obscure content or large archives. Someone only cares about the data once a year when doing research or something. This network won't solve this because there is no profit in storing data that is very rarely archived. Its a hard problem because you need to rank data on how valuable it is.

A dump of GeoCities is rarely used but has great value. A 1tb archive of videos of me counting grains of sand is also rarely used but worthless.
