According to Merriam-Webster Online, anarchy is "a situation of confusion and wild behavior in which the people in a country, group, organization, etc., are not controlled by rules or laws"
By that definition, I feel like it would be impossible to call a working thing "anarchy."
Yes, semantics are fickle; one word can hold
a hundred different meanings. In the context we're speaking of here, we refer to the political philosophy of anarchism, not the synonym of chaos, which can be briefly summed up as a society revolving around voluntary interaction:
Anarchism is a political philosophy that advocates stateless societies often defined as self-governed voluntary institutions, but that several authors have defined as more specific institutions based on non-hierarchical free associations.
This is why I don't like anarchism; not because I disagree with the philosophy, but the word is beyond repair, so much so common dictionaries fail to define it properly; here's dictionary.com's take on it:
an·ar·chism [an-er-kiz-uhm] Show IPA
noun
1.
a doctrine urging the abolition of government or governmental restraint as the indispensable condition for full social and political liberty.
