In my head libertarians are the right and anarchists are the left but they are similar in ideals (little to no government intervention). At least in the sense that if you talk to a libertarian I feel they tend to sound socially right and an anarchist tends to sound socially left. I have no idea if this makes sense at all. If you’re going to tell me to read more, sure, recommend some literature though.
Libraries are very much in line with anarchist ideals like education and sharing resources, and are pretty counter to libertarian ideals of private ownership and non-dependence.
