The author is a lot more optimistic about the growth of legal support for cooperative enterprises than I am.
Under capitalism the overlords (ruling class) like to see working people competing against each other as they enhance the profits of capitalists. As for capitalists themselves, they really don't like competition as evidenced by the ever greater concentration of corporations and the frequent reports of business collusion and price-fixing.

As the ground swells with people adopting more sharing and cooperative work and lifestyles, we can look forward to a growing body of law and literature on the subject.
