Yet our society is mostly not top-down. No one dictated what will be the next new word to come into existence. Nor is there a commissar that tells us what recreation to enjoy or even how to enjoy it. Seems humankind gets along just doing stuff and figuring out how to organize on it's own without top-down for all aspects of our lives.
