One of the reasons for pirating is that there are no ultimate and afordable source/s of all the content. Actually there should NOT be single centralized entity which would hold the informations/data, making single point of failure (SPoF).

By distributing the content, the risk of inaccessibility of it is decreased. That is why P2P networks like Gnutella, ED2K, Direct Connect, Soulseek and others are used.
