There is always debate over the extent of "free". At the extreme, the state doesn't enforce land property and the landlord is responsible for hiring an army to protect some land. In a more moderate situation land and property are organized and enforced by the state, because this protection is more efficient for everyone. Intellectual property is incredibly hard to enforce, because anyone can copy an idea, or bits on a hard drive, so you'll have to come up with convoluted solutions to check for the presence of information at every point in a network, and we're expecting citizen to pay taxes to pay the police force who will enforce those rights in favour of the owners. There are other, more efficient means, but they involve the richest to get a smaller cut (e.g. instead of the state enforcing DRMs for free, they have to pay for good DRM themselves), so it's very valuable for them to leverage the state to enforce their self-proclaimed rights.
