Philosophical communism, most famously described by Marx, is a utopian state where government has withered from lack of need as society evolves from capitalism to socialism to communism. That of course has never existed.
What most people mean when when they say communism is a corruption of the idea that has been used by Lenin, Mao, and others to create governments that they claimed would lead to communist utopias. Even that corrupted version requires that the proletariat, the people who sell their labor, become all of the people and be empowered as equals. It requires, at least rhetorically, that the government be subservient to the people and that the people equally control the means of production. Did any of the governments that we identify as communist ever live up to that? No state has ever actually claimed to have achieved communism, (e) in fact most haven't even claimed to have achieved socialism. The USSR considered itself to be the most socially advanced state post 1961 and called itself a developed socialist state.
