This is true of black markets but not the Mafia. The Mafia is a group of people that are powerful enough to extort another group of people. Black markets created by government prohibitions fuel Mafias no doubt, but a Mafia is just a group of guys with guns and subsequently power.

But violence itself doesn't scale. There are no nationwide networks of, for example, purse snatchers, or kidnappers, or bank robbers. It is only when prohibition creates black markets that large-scale organized "crime" can emerge.
