Rosa Lutzenberg's Critique of Communism

Luxembourg's Rosa Lutzenberg wrote in 1918: 'Let Ukraine be a nation. One day the central party will pull them back' She was arguing for more unity and less control at the beginning of revolutionary socialism, he says. Was she right that ultimately communism doesn't just coexist with freedom, it feeds off freedom? Instinctively I doubt it, but who knows, because as many people would say in this kind of argument, the Rosa Lutzeberg version has never really been tried.
