You are missing an important point. Fentanyl is loved by traffickers because you can order it from China and its extreme potency means it's easy to sneak across borders. Moving an amount the size of a brick across borders and then selling it as oxy or cutting it into heroin could make tens of millions of dollars on the street. This extreme potency, however, means that it must be mixed/pressed perfectly or you end up with "hot spots" - a chunk of fentanyl in a pressed "OxyContin" pill that's fatal.
