Anthony, you are so right. The pro-IP libertarians ought to hang their heads in shame. If they support this result, it's unthinkably evil. If they oppose it--well, they really can't, can they, since this is the result of having a state-run IP system--of having a state at all. Every IP advocate is a minarchist; you cannot have IP without state legislation. But once you have a state and empower it to "make" law artificially, you can't complain about the law it does make--especially if it is IP law and you support IP. As Mises said, "No socialist author ever gave a thought to the possibility that the abstract entity which he wants to vest with unlimited power—whether it is called humanity, society, nation, state, or government—could act in a way of which he himself disapproves."
Libertarians who favor IP--who want to continue to be able to honestly call themselves libertarians--should look in the mirror and think twice.
