The Constitution wanted artists to have control over their works because they knew it would create incentive to create more works. That is clearly still the goal.

There is no sense in owning the copyright unless you are going to use it. I don't think anyone wants to hold all of this stuff in a vault and not let anybody have it. It's only worth something once it's popular.

The enforcement is the flip side to the growth. And that's OK.
