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.
Every gram of unreported gold you own buried on your backyard is also considered criminal activity. What's your point? If you don't want to be monitored, as far as using metals goes, it's useless unless you live in an local Amish type community doing commerce strictly within those borders as anything outside it would get quickly confiscated. Anyone that has a real business is going to need to settle transactions globally for which gold is completely useless in the 21th century. Customs are monitored way tighter than Bitcoin transactions.

I took a much needed break from posting on internet forums.
