Another Folly of the Net Neutrality Concept

The following just occurred to me:

Proponents of "net neutrality" argue that allowing ISPs to offer some websites at a faster browsing speed compromises our access to all those websites offered at a slower speed.

However, in a free market system, those slower websites would have every incentive possible to create a faster browsing experience that offers comparable accessibility regardless of ISP speed. In this way, the net neutrality movement is a strong disincentive to improve website content efficiency.

But do I have a real-world example? Sure, I do. Remember the days before Facebook, when MySpace was the preferred social networking site of most of us? What ultimately did MySpace in was the clunky website mechanics, slow overall speed, etc. Facebook was superior because it was streamlined and much, much more efficient.
