This is why I invested in Monero years ago, when it was under a dollar. I concluded that since the only actual application of crypto up to that time was selling illegal goods and services on black markets like silk road, that it was really the only coin that made sense at the time (I'm sure others replicated it). AFAIK it is still considered untraceable, but the value peeked years ago around $400 IIRC. I made some decent money on it though and still HODL some.
Many people would think it's ethical, if anything morally positive. Do your part in demonstrating to the govt that if it plays stupid games (in this case, seeing if Prohibition would work better the 2nd time around), it would win stupid prizes!
