I think that in the end it may not matter; if i had to classify "real" art and was thinking clearly, i'd say "real" art is the message that the piece carries, as the piece itself is just wood, stone, ink or whatever, can be defaced, taken off a wall and sold to a rich guy's living room wall whereas the message is intangible.

So i guess censorship would actually be the worst case.

Ps. This line of thought relates to some of the other comments in these threads ("... [T]here's no protesting capitalism. There's nothing you can say about capitalism that it won't subsume and sell back to you." https://news.ycombinator.com/item?id=10093768)
