You mention money. Why is it important that it's free? Is there something wrong with trying to be paid for your work? I don't totally agree that artists should be thought of in the same way entrepreneurs are. Saying that the person who wrote a song shouldn't be able to stop people from sharing it is like saying Samsung should be able to install iOS on a tablet and apple should find a different way to monetize their platform.

And as for culture, well culture is created by all of us. You or I or the next guy may have good taste but that doesn't mean the majority do. So when this ridiculous amount of creation goes on that means there will be far more crap than gems and with so much crap to wade through eventually it'll be lost and Lolcats will be considered culture and it'll be a sad day for culture. I'd like to believe that good things survive, I really do but that seems too optimistic to me. The music you've discovered wont be considered part of the culture of the future. Lady Gaga will. That's just what happens when there's so much to choose from.
