I have created an AMM for NFTs where you launch a collection in a smart contract and every one can buy and sell whenever they want to the AMM contract. I think this is the only way NFTs can come back. The problem originally was that NFTs couldn't be sold if the interest drop. With similar contracts this problem is fixed.
What do you think about the idea? Here is the code in solidity:
