The article defines the "commons" as sharing the meager resources available to the masses. But if we are one society, the commons are the property of the society as a whole. As technology increases productivity it also reduces the need for labor. So the wealth moves to the owners of the tech. Society can't survive unless there is a mechanism to re-distribute that wealth. It will happen by progressive taxation (like the 90% top marginal rate in the Eisenhower administration) or it will happen by revolution. I think everyone (including the rich) would prefer that it happen by taxation.
Our country does not exist to serve the theoretical construct of the "free market" (which of course is highly manipulated and not at all free). It exists to serve the people who live here.
