Well, at that scale tariffs on other things could be used as a cudgel to encourage enforcement on the Chinese facilities by China, sure. There would still be some fentanyl available, and opioid users are fairly flexible with the specific opioids they use. Heroin, oxycontin, hydrocodone, codeine, and such tend to come from elsewhere. As one lab in China shuts down, another in China could pop up. Or in Nigeria, or in Pakistan, or in Venezuela. I lived in Missouri before we had to sign for psuedoephedrine. Trust me when I say busting a lab here and there doesn't stop production. Reports I've read say you can invest $4,000 to easily make a kilo of fentanyl and after cutting and distribution it's worth $1,500,000 ( such as https://www.gangsterismout.com/p/fentanyl-w18.html https://www.gangsterismout.com/p/fentanyl-w18.html ). Carfentanyl is supposed to be basically as easy to make and about 100x as powerful. This leads me to believe no state sponsorship is required to quickly ramp up production. If you can sell a $4k investment for over a hundred million dollars, you can ramp up quite quickly for your next several thousand kilos.
