Is there any law in place preventing an airship from loitering?

So here’s the scenario. There’s nothing that I can think of (except maybe some kind of blanket law) that would prevent an airship from loitering in the Golf airspace around a city. The catch is that I’m also wondering if it would remain within the realm of legality to maneuver said loitering airship so that it blocks out the sun throughout the day over a patch of land without the land owner’s permission… please don’t think I’m plotting evil deeds. This is just a hypothetical situation that wandered through my head. In general, I’m also wondering if the FAA already has any plans in place to handle weird potential contingencies like the one above. Thanks in advanced.
