True Communism has never been tried

Western leftists conviniently forget the 3year period of War Communism in Russia, a brief experiment with "True Communism" that failed so hard, Lenin started NEP(new economic program, semi-centralised market economy) to allow USSR to survive.

NEP isn't communism. It was more similar to Hitler's socialism, where state controlled large enterprises, but still allowed small scale free market.
