Just because the marginal cost of a copy is zero does not mean there's no value in the information, and it's perfectly reasonable to gate access to that value.
Copying a video file is free too but I'm sure you wouldn't argue that anyone can watch a movie for free just because someone else made it. People have a right to own and control the distribution of their works that they invested in creating.
