This is already doable with most wallets today. Most wallets enable you to create 2^64 addresses from the same seed phrase. These are hardened and can't be linked together by just creating them.
So if Alice wants to send Bob an NFT, Bob creates a new address (recoverable with the same seed phrase) and Alice sends it there. Bob can then fund the wallet with tornado cash to use the NFT.
It's a stupidly complex way to achieve privacy and Tornado Cash is illegal. That's why we need private by default chains like Aztec & Aleo
