You're missing my main question. I'm not looking to do anything sketchy like private sales or cash deals. I know about non KYC Bitcoin and markets with peer to peer meet ups. Not interested. 
If I needed to sell now I'd go through an exchange and report the transaction.
I'm looking for legitimate ways to sell Bitcoin in the future. Maybe a tax loophole. Does anybody run it through a corporation somehow? Friend or family overseas and then back in dollars? 🤷🤷
People avoid tax in fiat world all the time. Surely someone smarter than me has figured out how to do it legally with Bitcoin self custody.
Or not. Maybe one day.
