For the latter, because that indicates a criminal enterprise. The idea of a coordinated group of people all breaking the law is deemed worse than one individual.

I can reconcile this with my own values.

Practically, an enterprise of criminals is more likely to be effective, and thus would create more negative costs.

Legally, it allows prosecution of the organizers of a crime group, who are likely the most dangerous and more difficult to catch in the act, as they contract others to do their work.

I am not a lawyer but in jurisdiction there may be a slight difference between crime and organized crime like between selling drugs on the street and leading a drug smuggling cartel. And training your employees how to break law could be also prosecuted.

Uber is being tried federally because their crimes cross state lines, which wouldn't be the case with one pizza parlor operating locally in one state engaging in the same behavior.
