Any Other Anarchists Here?

Actually, there have been successful anarcho-capitalist societies, the most famous of which being the Icelandic Commonwealth (930 to 1262). Another well-known example is Celtic Ireland (650-1650). Bill Orton wrote a concise summary of life in the Icelandic Commonwealth and Celtic Ireland, among others, which can be found here:

Finally, if you have a bit of time to kill, historian Jesse Byock wrote an entire book on the Icelandic Commonwealth called Viking Age Iceland.

Anarcho-communism has worked as well. Look at the anarchist communities during the Spanish civil war.

The Spanish example, in which high levels of mobilisation and swift improvements to production were implemented by anarchists, is often cited as an example of an anarchist-communist society which saw rapid improvements to both industrial and scientific output.
