Governments have presented us with a third option, intellectual property, which allows a creator to release their intellectual contributions publicly while preventing someone else from reproducing it. Violating the terms of an open source license are generally considered intellectual property violations and allow the creator to seek damages.

Good luck with that. If you throw your wallet onto a busy street corner, then by the law nobody is allowed to take it either. But cops will tell you that they have more important things to take care of than victims who take every measurable action at hand to make themselves victims.
