This may sound dramatic, but it's true. Because if an unlicensed (non-privileged) person is operating in the market, even if they are reasonably qualified, they will still be targeted by the state on behalf of the licensed (privileged) lobby: First, the unlicensed person may be fined. If they refuse to pay the fine, they may receive a warrant. If they refuse to go to court, agents of the state will knock at their door, threaten to lock them in a cage for not paying their tribute, and ultimately use physical violence to force compliance.
