Meanwhile, for example in Spain in the same time period, there was a remarkably broad activation of the population in revolutionary activism and political engagement, which allegedly doubled productivity and dramatically increased agricultural yields, which to me indicates that the anarchists were basically everywhere (how else did they syndicalize such wide swaths of the economy?).
