To preface this, I'm 50/50 on this one. I understand
why
the system is set up like this, it just seems strange to me that the current implementation of "instance settings" allows people to disrespect a world creator's wishes if the instance isn't public.
If a world creator doesn't want people to stickerbomb their world or litter it with prints, then I can see why people would argue that that choice should always be respected.
This is especially worrisome when drones are currently able to influence rigidbodies: https://feedback.vrchat.com/open-beta/p/1601-drones-should-not-influence-pickups-rigidbodies-in-worlds
