Piracy and dismissal of copyright isn't an egalitarian act of rebellion; it's a humanist recognition of the right of any person to freely engage with the world around them. I have enough material wealth, and if I make something that's actually useful it would be great to see people building versions of it that better suit their specific needs.

That said, it is fun to say "fuck the man", and often doing the right thing coincides with it for a while. Rhetoric like that can be a good way to get some people out of their comfort zones on topics like copyright, and then more nuanced analysis can lead to the realization of the importance of building sustainable, respectful means of production. DRM, Copyright, etc. are net losses to society. They may be the only way 100mm-dollar-budget movies can exist, but I think it's better to have a culture where the people have democratic control over the objects of their culture instead of being at the mercy of content conglomerates, cease-and-desist letters for fan works, and geographic youtube restrictions.
