In a profit-less or reward-less society, what reason would there be to work? None, unless you essentially become slave labor.
A lack of profit doesnt mean there is a lack of reward, the reward just becomes personal like it should be. Money just gets in the way.
Piracy, however, comes from people who break the law in order to steal free copies of software that companies put a lot of their resources into.
Piracy is just one of the many effects of not sharing. You could say its the system itself that creates a divide between the haves and have nots, which leads to the have nots to take what they feel the haves have taken from them and the haves to protect what they have even more feverishly (DRM, Trusted Computing, DMCA, take your pick)
I don't really understand why you're even posting this here. This is a thread about copy protection
And piracy both of which are ethical or even philosophical problems. Hence my reply.
Anyway, if i went too off-topic i apologize to the forum gods =)
