You are paying some tax, just not all the required tax. Specifically you are evading income taxes. As I recall in the US at least, there is an option on your IRS form to report any income derived from illegality so that the relevant tax can be paid. Whether anyone has ever done so I don't know but something like that could have kept Capone out of prison.

If you illegally sell $10 worth of drugs, then record your front store of selling $10 of Tylenol (that you don't actually buy or sell) then the $10 of drug money has been fully taxed.

There's taxes from the supply chain of Tylenol that don't get paid when it's $10 in illegal drugs that are actually sold. Much like Bitcoin, with a black market you can only tax at the egress points when the money needs to touch a regulated financial entity whereas an all-legal system can tax any time money changes hands.

Certainly that's someone else's crime, and they need to launder their own proceeds.
