We also didn’t have a better way of doing math than an abacus for thousands of years. If Anarchy could regulate then we wouldn’t need all these laws about minimum wage, not using children as disposable machine tools, and not putting rat poison in their food products. Clearly there is some need for a body that can do that. And at that point, You’ve got a large centralized national body again because you’re going to need to vote for who you trust to do it, they’re going to need the physical capability to do it, there’s going to need to be taxes to keep it all going, and oh look. We have a national government again.
