That's maybe true for mainstream places, in particular online. If you look at all the nonsense about the metaverse for example, before it even existed people were coming out of the woodwork complaining about the possibility of virtual groping and other silly stuff. It would inevitably have become some boring sterile place that reflect a bunch of values no real person has

The same is apparently true in the real world for Disney properties (though I'm sure it's more played up than it actually is)

That just means that being an interesting third place is incompatible with being widely known.
