OK cool. Society determines copyrights - I think that's good too. Most people think those who make stuff get to determine the price they sell it for (except a few rare cases, eg AIDS medication), so that's what the law states.
Salt Satyagraha was a protest against a government tax, by those in favor of free markets - not a protest against free markets. See the link you just posted.
I brought it up as an example of a society in peaceful revolt against a high price for goods, doesnt really matter who was setting the price, a tyrannical government or producers. They had civil disobedience which has a few similarities to how people flout copyright laws today (not completely the same of course, since they were willing to go jail). Like charging high prices for access to something that's essentially free (salt then, copies of mp3 files now)
Also see how electricity is commonly stolen in developing nations, anti-prohibition activities etc. For examples of societies trying to act through government to regulate payments to people, look at the UK bank bonus tax or the Autralian attempt at a mining super profits tax, and in the other direction blank media taxes, farm subsidies etc.
