Who cares?IMO Most D&D players want nothing to do with authorship. At least not on any level beyond, I swing my sword at that orc. I try to look intimidating to that goblin. I search for a secret door. I move to block the door.
That's the limits of the authorship powers they want and that's very similar to the limits of authorship powers in LARPing.
The fact that some people don't like chocolate ice cream doesn't stop chocolate ice cream existing, or being valid as an ice cream, or tasting differently to strawberry ice cream.
