A startup society is typically a small territorial experiment in government. For centuries, innovators have created enclaves to escape institutional barriers. America itself was created to escape religious persecution in Europe. The startup societies of today are making the world into a more diverse and competitive place.
Since the foundation of society is good governance AND "good government" means different things to different people, new startup societies can improve lives by providing a space to experiment with new ideas and provide competitive pressure to existing states.
