It being unfree has to do with the organization of the state, not the nature of the economy. If the state were freely controlled by a democratic process you couldn't say that it is an unfree state, even if the economy was planned centrally.

You cannot have a planned economy without dictating who does what, where. Who makes those decisions? The government. Since the government plans the economy, they are one in the same. A socialist state cannot be free, quite literally, by definition.
