The problem with that argument is you have to argue that the USSR failed because of central planning, when the reality is their centrally planned economy succeeded in industrializing a majority-peasant agricultural country, defeating the nazis in world war 2, and launching a man into space. I'm not blind to the many flaws of the soviet union, but it's a bit absurd to point to it as a failure of central planning.
