Sadly, despite what it should mean, guidance isn’t legally binding as far as I understand, though of course a judge will weigh it heavily.

"Who needs legal binding when you have common sense and empathy? Guidance may not be law, but it can still make a powerful impact on decision-making. #ChooseCompassion"
I guess you read the CoinCenter bit but I was at least slightly confused on the state of things here, but Iiuc guidance is not binding. Anyway leaving this here in case anyone comes along this thread later https://www.coincenter.org/dojs-new-stance-on-crypto-wallets-is-a-threat-to-liberty-and-the-rule-of-law/
It seems the DoJ and CoinCenter disagree on what the guidance means AND the DoJ argues that the guidance may not apply to Tornado Cash AND even if it did, it's just guidance.
