A communist society is characterized by common ownership of the means of production with free access[1][2] to the articles of consumption and is classless, stateless, and moneyless,[3][4][5][6] implying the end of the exploitation of labour.[7][8]
That was not the case. It was state owned, as the transition from whatever system was there before to socialism plans. Communism is supposed to be something different.
I am not arguing that it would be good or better than anything we have today but am saying that we never saw communism in the modern world.
