I personally split the difference now. I think if the hive mind was completely rational, liberty/ancap must work in principle.

But propaganda, and moreover just how much violence people are raised with even still on average in western households, let alone the insane variance in parenting quality from China to the hyper religious Middle East to the current lead-filled (or micro plastic filled?) brains of Trumpers to the insane gang violence of Mexico and South America to the total rape of the continent of Africa… prohibits there from being any volume of rationality required to make it possible for at least another 200 years.

…except before 200 years we will have needed to solve for all of our global crises anyway to avoid extinction (at least there is a non negligible chance)—and thus some mix of socialism via the state, and the “market” AKA Earth dying, with the occasional bout of rational zeitgeist, is the only way to save Earth and explore the stars.
