I wouldn't say it was obviously off limits. It has been retrofitted by users for recreational use. Completely wide open access to premises, the building, access road.
Is it equally "obviously off limits" when those semi-trailer /RVers are frequently parking in Wal-Mart when they come, sleep, then leave without going inside at all, but one of them injures himself on the lot? would they be "privileged" because people are doing this and store is aware, and is not showing objection or "without privilege" as Wal-Mart don't provide their parking lot as "camp ground"
I see it as former...
