For a large scale, permanent anarchist society to form, (like hundreds of thousands to millions of people), a seismic shift in mentality must happen. On the scale of people moving from monarchism to democracy, and feudalism to capitalism.
For most of human history, slavery was considered a foundational aspect of society, people couldn't even imagine society without it. An average ancient person would have thought you were absolutely crazy to suggest that a large scale civilization could work well and be prosperous without slavery. Same with a monarch, same with changing a feudalistic system to a market-based capitalistic system.
My dream is that one day, people will look back at current the era of statism in the same way that we look back at the days of slavery or absolute monarchism. That one day people would be shocked that the average person believed statism was the only way to organize a society.
The best we can hope for right now is to keep educating people, and work to act out anarchism in our daily lives with others. Participate in mutual aid networks. If nothing like that exists in your area, find a few like-minded folks and form one. Support open source, decentralized software and forms of media. Oppose hierarchical systems around you, subvert capitalistic markets and companies, protest and fight alongside fellow leftists and try to sway them to our side.
We will likely never enjoy the shade of the tree we are planting, but if it grows and blossoms one day into a great canopy, our efforts will have been forever worth it. And if not, then at least we can say we lived our lives true and free, fighting for the way things ought to be.
I'll check it out. Even if it doesn't work conceptually, it's still cool to think about alternatives to the Capitalist markets and currencies that are dominant.
