Concepts where (mostly) everyone agrees that not everyone agrees about whether the thing exists or not, but if it exists, it probably has agency, like divinities.
Orders that people seem to agree exist, even though it’s unclear how to judge them, like “the best band in the world”
Objects that when imprecisely called can be either rigid body or ideal gas, like “water”
FWIW, my feeling at the time was, “this is fun, I enjoyed this, but 1. I don’t want to monopolize this experience as there’s only one ball to toss and 2. I’m getting increasingly worried of bonking someone on the head”
I think this might just be a non-ideal case study of the point you’re making, though I do agree with it generally
