Those states, according to theory, are meant to be a transition TO communism, but of course many things can go wrong in that process, and we're kinda right back at the situation portrayed in the meme.
Despite my spat with the ML leftists in this thread, I see why the idea of a communist Vanguard state is appealing. I also see how a state which transforms into socialism or communism must be "authoritarian" in that it has to take away factories and land from those that keep it as capital, so that it can be shared. These states also had to contend with constant sabotage and aggression from the Liberal Democracies of the West who feared worker revolution coming to their own land.
Anarchists are a more idealistic bunch and generally strive to build parallel power structures and organizations of people and so try to construct a new order upwards. In practice it's hard to imagine that method being able to replace nation states, especially with similar external sabotage on top of the existing internal challenges of running an equal society. Dictatorships and blind supporters of authoritarian leaders are hard to best in terms of efficiency.
Both approaches seek to accomplish communism, anarchists want to have their dessert right away, Marxist-Leninists believe the wolf will take care of them just as soon as he's done eating his enemies.
There has never been a communist state, not as a cop-out, but because there is no state in communism by definition. These states claim that they're transitional towards communism.
