>there are plenty of under the table ways to sell virtual assets for real money.
But are there any games where you can plausibly put real money in and generate excess gains in virtual assets in a short time? You can double your money in a casino in seconds, but the only way I know to extract money from video games (even play-to-win video games that milk whales for a lot) is arduous and slow gold-farming.
I agree with your take on NFTs. They would have been used that way if the NFT games hadn't basically all been Ponzi schemes. Like the pachinko gambling loophole.
