One could also argue that if the developers did that, the market value of the digital item in question would drop. The value that the buyer receives is grounded in the large time investment required to acquire the item in the game. Even though it is completely artificial, it makes the item more scarce and therefore more desirable to other players. I totally agree that the fact that this power is in the hands of the developers, though, makes these types of NFTs far from the decentralized digital goods they are claimed to be as pointed out by the author.
I think it's not even necessary. Otherwise, rights holders wouldn't have to put in so much effort to hold up the other form of artificial scarcity, DRM. Free software wouldn't exist.
