> but being a culture that tends to tear-down fences has the second-order effect of being more adaptable.

By killing many. In biology, species with higher rates of genetic diversity in their offspring sacrifice most of there offspring. E.g. trees fall into that category. Their seeds have more genetic diversity, when compared to children of mammals. But a single tree can produce tens of thousands of seeds in one year. And the environment conditions can change drastically every few meters for those seeds. Therefore, it is a successful strategy. But most seeds never grow into mature trees. Do we want to model human cultures on that strategy?
