Can be summed up by pointing out that if we could make an exact copy of our food in order to feed the poor without losing anything, we would have a moral obligation to do so.
I.P. is a politically created property. True property is concrete, and if one steals true property the owner suffers the loss of that property. With I.P. one merely suffers the loss of an expected advantage.
In addition, much of what passes for popular culture today is protected by I.P. A large motive behind various forms of entertainment and propaganda is the desire for profit. We are easily drowned out. In a world without I.P., those serious enough about their message to incur costs trying to get it out become the dominant players. I think that means more American children would grow up learning what faith actually means, rather than growing up with the Disneyland version- "If you just believe hard enough, it will come true!"
Intellectual Property benefits a very few, mainly corporations, and puts snares before the poor.
