> No, that is just one example of a payload - the token itself is non-fungible, so presumably some one could write code to associate the ownership of that token to some game feature. Lets say a mount in WoW, then you could trade said token as part of a secondary market.

I don't know why you started your sentence with "No". What you describe is exactly the same as buying the name of a star, except it's on blockchain instead of some kind of database.

If you like, you can write code to associate the ownership of that star (by access whichever star registry institution you like) to some game feature. Or you can let the player submit a "star ownership certfication. It's just the same except the data source is decentralized.
