Valve relentlessly rent-seeks the secondary market, making it impossible to trade the skins for anything useful. They have gone out of their way to end any way to exchange them with any real world currency, because it then ends up being akin to gambling. Valve is almost a despot, exchanging skins as NFT would take these powers out of the game dev's hands, that's the whole point.
