The Pirate Bay trial just growing pains, look back at 10 years of piracy

It's simply more convenient for people to pirate material that they can use hassle-free - no software compatibility hassles, bizarre hardware restrictions or archaic region coding.
As soon as someone decides to make their catalog of movies available, DRM-free, they'll reap the profits from the average consumer who just wants something simple.
The amazing thing about DRM is that it manages to be even less convenient. People would pay for a simple just-download-the-high-quality-file system.
Private trackers have most of the others solved as they tend to (always?) revolve around a seed to download ratio system where friends of mine have no problems filling their 100mbit connections.
I agree with your points though, a centralized no-hassle store has benefits over having to sort through public trackers it would be more convenient. Unless pirates start getting really good at social filtering.
