There have been some things that get pretty close. Kibbutzs in Israel simulate much of the "live peacefully with neighbors" but they tend towards collectivism.

The problem with going whole-hog anarchism is that on any significant scale (even a couple hundred people) peer-to-peer trust breaks down and anything that steps in to make processes more streamlined and reliable or introduces organizational structure becomes functionally equivalent to a government. We rely to such a huge extent on specialization of labor and trust of abstractions that such freedom doesn't scale if one expects modern amenities.
