Perhaps look into CoinJoin with wasabi's blinded bearer signatures as an improvement for the classic "dude hosting a website for tumbling coins" approach.
In the eyes of the govt it's laundering no matter how you try to obfuscate it. Bitcoin is a govt tracking and control system that abolishes the 5th amendment. Stop pretending that's not what it is and stop pretending the govt is ever going to allow you to tumble anything without being considered doing criminal activity. If you don't want to be monitored in real-time by the slavechain, then you should boycott this garbage and use physical metals instead.
