@glenweyl @joshgans I would even say that economies of scale in extraction tend to be larger than economies of scale in production; that is, the optimal country (or company) size for peacefully doing useful stuff is lower than the optimal size for extracting rent by being a tough guy.
@glenweyl@joshgans我甚至会说，开采的规模经济往往大于生产的规模经济；也就是说，和平地做有用的事情的最佳国家（或公司）规模低于作为硬汉获取租金的最佳规模。
