Also, I think the piracy will kill cinema argument is invalid. Piracy has been around in it’s current for since 1999, when Napster first came online. It’s been more than a decade, and despite piracy, blockbusters are still getting made, and movies are still profiting, even making record profits in some cases. If piracy could kill the movie industry, then considering piracy has been widely active for over a decade, it would have done so by now. It doesn’t seem to even be hurting the industry any more than the loss of shoplifted DVD’s or VHS’s would before the Internet came along.

I think that both your garden variety YouTube videos as well as your blockbuster cinema movies are culture, they’re just two different types of culture and art. Both should be preserved, and piracy has made no clear threat to the movie or music industry. In fact, the only evidence ever produced by someone involved in those industries proves the exact opposite. http://torrentfreak.com/former-google-cio-limewire-pirates-were-itunes-best-customers-110726/

because file sharing is not illegal, hence the above statement is too vague.

it should be more clear: i.e. “decriminalize the sharing of copyrighted material for non-commercial purposes”

but even then how do you quantify “non-commercial?”. if i start a torrent community and it gets really popular after a few years, mostly due to the free publicity I was borrowing by providing highly publicized, popular content, and i have to bring in revenue to maintain it and pay costs associated with it, i am then a commercial entity. will i then have to retroactively pay the royalties? my user-base was generated through “non-commercial”, free file sharing, but now they’re generating revenue. how do you legally guarantee the autorities that your sharing activity isn’t for commercial purposes? without a time machine?
good luck fighting through that legal quagmire. it’s a tangled problem which won’t be sorted out any time soon. but to eliminate copyright altogether would result in an even larger problem. and a huge rights issue.
the answer is in creative commons. creating and sharing material using these licenses eliminates the above legal nightmare. that’s what it’s there for, so USE IT!

the quote at the very top is merely one example of how the anti-copyright movement keeps confusing itself, incorporating misleading information either accidentally, incidentally, or intentionally, which does not help the matter at all.
FILE SHARING IS NOT ILLEGAL unless the creator/owner/licensed distributor clearly prohibits you within the limits of the license they provide with the purchase. that is their right if they CHOOSE to do so.
anyone creating media can appreciate this right. it encourages innovation on the part of the author

nice work :D
