Huh. I definitely have the feeling that the difference is more than just information being non-rivalrous, but yeah it can't be as simple as I was trying to think... . Didn't absentee land ownership used to be looked down on? Maybe that ties in somehow. Trespassing, there's https://en.wikipedia.org/wiki/Freedom_to_roam https://en.wikipedia.org/wiki/Freedom_to_roam so it sounds like it's not nearly universal and at least in some places tied to liability concerns and (potentially) interfering with the owner's use of the property. Maybe with IP it's that the owner/creator can't know unless they're told or actively go looking? But then that more-or-less gets back to non-rivalrousness. Hm. Some information actually does have effects if known/used, like a successful stock trading algorithm. But then that's not "artistic", and brings to mind that IP is more than just patents and copyright.
