Every ideology exists on some kind of spectrum. As far as I can tell, pure capitalism, pure communism, and pure anarchism all bring significant problems when you try to apply them that are unique to their own strengths and weaknesses. You have to work things out and use common sense. But, talking about political philosophy and trying new principles for governance can still be a good thing, even if the as-described form is often a failure if people try to apply it in a way that is “pure” ideologically.
