Of course it is. Anarchism at scale just needs a reliable way to keep criminals (governments, rulers or otherwise) from stealing private property and violating the non-aggression principle. This isn’t hard on a micro level but it’s been impossible at a macro level. 

It’s the 1% of sociopathic humans that gather power and fuck it up for the 99% who inherently cooperate. 

Many native societies largely operated on anarchist principles. There were vague hierarchies but members of societies were absolutely free to leave at any time if they didn’t like how they were being treated as well. There was very little commanding and a high degree of personal sovereignty, no taxes, and cooperation was the rule. No threat of violence for making your own choices. But they all had to be hardcore warriors to protect their shit from others.
