You can't restrict ownership of physical goods or art really, it's just that there's "authentic" goods and "fake" goods.

So you're right you can't restrict possession of digital goods but you can restrict the right to sell a digital good because any potential buyers will want to know what they're buying is "authentic".

CSGO skins go for thousands with the rarest going for tens of thousands, you can download them and possess them right now but valve says you don't "own" them and can't sell them.

CSGO skins are a slightly different case because of their use in-game. You can't play in an actual competitive game of CSGO with a knife/skin that you don't own.

Yes, there are servers that will let you try out custom skins and knives but you can't play an official game with them. The knives also offer different animations which look cooler than the default one. It's slightly different to me in that there's no inherent usefulness of the NFT's (at least currently - maybe in some metaverse future they have a use).

It doesn't seem like people really want to "own" the NFTs, they are viewing them only as investments which means eventually someone will be left holding the bag. In contrast, people DO want to own the CSGO skins and knives.
