An important reason for the Internet's remarkable growth over the last quarter century is the "end-to-end" principle that networks should confine themselves to transmitting generic packets without worrying about their contents. Not only has this made deployment of internet infrastructure cheap and efficient, but it has created fertile ground for entrepreneurship. On a network that respects the end-to-end principle, prior approval from network owners is not needed to launch new applications, services, or content.
In recent years, self-styled "network neutrality" activists have pushed for legislation to prevent network owners from undermining the end-to end principle. Although the concern is understandable, such legislation would be premature. Physical ownership of internet infrastructure does not translate into a practical ability to control its use. Regulations are unnecessary because even in the absence of robust broadband competition, network owners are likely to find deviations from the end-to-end principle unprofitable.
