There are good reasons why money laundering is illegal tho.
Discussion
TBF Money laundering is defined as 'the process of making illegally-gained proceeds (i.e., "dirty money") appear legal (i.e., "clean")', so if you are just trying to obscure where your legitimate money is coming from for privacy/safety reasons I wouldn't consider that unethical.
Well, good luck explaining that to auditors or investigators. Ppl that use coin tumblers like tornado cash are literally conspiring to launder the proceeds of crime, that’s what they’re generally used for.
