Erm...I suppose one might be able to argue that, by stretching the definition of "totalitarian" somewhat.
And yes, true communism really is people living voluntarily together in a commune. Any kind of central government makes it no longer truly communist (at least, based on my understanding of communism).
Socialism does require a central government, but does not require totalitarianism, unless you want to define any level of government control as being "partly totalitarian," much as the social programs enacted in the US over the past century+ make us "partly socialist".
Yep. Communism works in a small scale, small communities and villages, but it falls apart in a big scale, provinces and countries.
China, North Korea and Soviet Russia were not true communist countries as everyone became poor except their ruling classes. :p
