Yeah, my analogy could have been more clear, I think Umarells are a fun cultural phenomenon.
I meant that even in a public space for construction, however, spectators usually aren't allowed to wander into the middle of active construction, bumping shoulders with the workers. Staying off to the side is fine – as is also normal when watching a set in action! It's just the folks that get in the middle of a site who have no business being there (or worse, try to pretend to be an authorized background extra and ruin a shot because they have no idea where they're supposed to stand) that disrupt things.
