Claiming that you've made an unsupported generalization, and then making one, is not a contradiction; it's hypocrisy.
In any case, your statement still fails to hold water. Consider the ISS: there is central planning and command of the entire economy of the vessel, from its air, water, and food to its electricity and the time of the astronauts themselves. But the 'point' of this command economy is not to limit freedom; it is to keep the astronauts alive. This is the most extreme example, but obviously there are other situations (ships at sea, camping trips with a group, military operations) where centralized control of the goods produced and services performed serve the goods of the group's goals, and have nothing to do with intentional limits on freedom.
