a famous part of the prohibition was the organized crime which was both kind of naturally occurring at the time and was created specifically to traffic booze

Quite a few political families profited handsomely from alcohol prohibition. The Kennedys are probably the most famous, but the political system was rife with corruption. If you’ve ever watched Boardwalk Empire, the story was based on the notorious Atlantic City sheriff Enoch Johnson.

So, turning to black market cartels is a form of resisting policing, it’s a form of anti-institutional action, I’d say, as it gives more economic power to anti-institutional organizations.

The ability to selectively enforce prohibition gives you ample opportunity to profit from the gaps in the system. Sex work has long had a relationship with local politicians and police, and I have no doubt that criminalization of porn would create an huge market for kickbacks to enforcement organizations.
