Sensible solution to open internet debate

At Hammer of Truth, Stephen Gordon's post about the open internet debate does a good job of summarizing the various positions on the issue.

My take on the issue is that overall, a so-called open internet is extremely good. The behind-the-scenes network should be invisible to end-users, and anyone anywhere should be able to access any website.

But instead of making a whole new set of laws that require companies to do this, why not just say this: Companies that restrict their end-users' ability to access website from another ISP lose their government-enshrined monopoly protection.
