One could argue that many modern right wing libertarians are closer to anarchism than some of their left wing equivalents. Back when I was on reddit there was much discussion of what they called watermelons - green on the outside, red on the inside. Meaning they presented themselves as anti authoritarian but in reality wanted to use the power of the state to enforce their ideal version of societal freedom. There are also differences in how the words are understood today in different places - Europe, the US, other places in the world. I did commend your historical representation btw.
