Sure, but WoW doesn't use NFTs to enforce scarcity.

What does a Google/Facebook/Microsoft metaverse want NFTs for? Once you start enforcing permissions on which issuers the metaverse honors, the metaverse might as well skip the whole NFT thing and use a database.

Well yea, if one company runs the Metaverse they don't need NFT's. NFT's are for places like Decentraland and other Metaverses running on Ethereum where there is no centralized manager of the world.

It's unlikely there will be one decentralized world (maybe a lobby of some sort, akin to a website directory on the early internet), but instead an Engine + SDK that allows anyone to build their own worlds and choose what NFT's are useable inside it. These worlds can be registered to Ethereum and then users can easily explore and congregate in whatever worlds they wish.
