The BTC ATM machine/company was presumably compliant with all local/regional laws and regulations. Taking responsibility for people entering shady markets is not the responsibility of our Justice system to parent with sawing through moral justifications. (Or, just make them illegal. But you can't have it both ways: Legal and we can cut your machines when we feel like it, or illegal and we allow you to exist.)
People have personal responsibility in the choices they make. BTC/ using an ATM also has many uses that aren't illicit or nefarious, and provide convenience.
Otherwise, ban (saw?) cash/bank ATMs. Because people use cash/bank account ATMs for illegal purposes as well.
