From Slashdot:
If I said I didn’t have an incentive to grow oranges unless I could plant a tree in your yard, or if I said I didn’t have an incentive to grow cotton unless I could own slaves on the plantation, most people would see this is these as the worthless shallow arguments that they are. But if I said I didn’t have an incentive to to make beneficial or creative works without a copyright monopoly, then all of a sudden people just take it on faith, they don’t even question it, they just assume that society would fall apart without them. In my humble opinion, this is intellectually dishonest, especially considering that the entire Renaissance happened without copyrights.
