Tankie here. I would agree on the following point -- that we are not the same. But, neither are communities where most people are respectful of others' liberties the same as, or suited to the same kind of rule as, communities where most people are authoritarians. Anarchism doesn't work among authoritarian populations.

In some places, there isn't a whole lot of class struggle -- I could see anarchism working in those places, but not with most modern people. Those are typically isolated places where people are self-sustaining and disconnected from modern industry, places where states can't naturally grow on account of the pre-existing lack of class struggle in those areas.
