Well, I'm not a socialist-thinking poster, but I've got an answer for you. I'm going to start from the bottom and work up:
Let's better define the question here. You're really limiting the options. "Pure" Capitalism is the world's only real remaining form of Market Economy, but we've had Mercantilism in the past. Command Economies include Socialism, but also include Communism, Theocratic Economies, and many Monarchies and Dictatorships where the government dictates who is allowed to transact with whom. Traditional Economies are basically every tribal and many smaller religious communities around the world -- rules governing transactions generally spring from several generations of tradition and often make no sense at all to outsiders. Most first-world economies, however, are Mixed Economies that allow consumers to choose who to transact with (as in "Pure" Capitalism), but only under restrictions placed by the government (as in Command Economies).
So right off the bat, your entire attitude presents itself as a false dichotomy.
They're artifacts of a Mixed Economy.
Neither. That's the false dichotomy. The world is more complex than your post allows for. There is more to an economy than "socialist things" and "capitalist things". The idea that everything ought to -- or even can -- be broken down that way is the result of hyperactive media working on ignorant minds.
What is there aside from capitalism and socialism?

If they're not CAPITALISM what are they? Why are they not SOCIALISM?
They're artifacts of a Mixed Economy.
Which of the preceding definitions...
