Well, if nobody is sharing files then nobody is going to be able to download them.
I think that people will even find ways around this recent tactic of the music industry. They have been pricing the consumer out of buying music for years and they had this coming to them. Like someone said, they could have harnessed this technology early on and turned it into another way to make money, but they were greedy and short-sighted. Eventually the law will step in also and protect peoples' rights. Some of this stuff goes way beyond constitutional IMO
