Classic Liberal, iolo, Damo, let's step back a bit.
The words "socialism" and "capitalism" aren't as detailed as you seem to think. They refer to very simple distinctions countries have in their industries. Socialisms have industry, agriculture, etc, controlled democratically - state ownership, municipal ownership, cooperatives, or some combination. Ctapitalisms have them controlled undemocratically. That's it. The application of these terms isn't reliant on government.
And countries with both these kinds of formats have certainly existed. But they typically have at least some small number of private firms within their borders. Venezuela, Cuba, Bolivia, Spain, Argentina, Russia, Yugoslavia, Hungary, and others.
Unfortunately, Iola is only taking his very obscure definition of socialism and proclaiming it to be the only working form or definition, and that all other (typically more common, of course) are not definitions of socialism. He has ludicrously tied socialism to political democracy. While his very communal and democratic form of socialism is probably the type you would be in favor of, he has effectively closed himself off from serious debate.
