It’s not so different from the old-school communists who claimed that a “dictatorship of the proletariat” is a necessary step towards the true freedom of mankind under proper Communism. Conveniently they were the ones in charge of the “temporary” dictatorship in this picture.
Libertarianism and communism are ideological siblings. Both fail time and time again, but to the believers it’s always someone else’s fault and the proper implementation of the ideology simply hasn’t been tried yet.
