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

Tornado cash is illegal for US citizens. Not illegal for anyone else. And a lawsuit against the overreach of the Treasury department will likely make it legal again.

What exactly is the "overreach" argument? In terms of statutory authority, the Treasury hasn't done anything particularly unusual in adding a known money-laundering vehicle to the OFAC list.

That seems different though, since Bob needs to give out a new address for each transfer.

With stealth addresses, once Bob published his public address, multiple senders can transfer to Bob without further interaction by Bob.

It relies on trusted hardware (SGX) that's been shown to be insecure many times. Please don't trust your freedom to SGX.
