Federal "net neutrality" regulations freeze into national law a particular formula for access, based on an idealized model that's never quite existed before. (To the extent the net has often been 'neutral', it's not because the FCC demanded it, but customers and businesses. And the legions of de facto exceptions have been practical, and evolving quickly, not waiting for telecom-lawyer mandarins in DC to design us a better internet.)
Even if new utility-style regulation prevents certain abuses, it equally prevents valuable experiments from incumbents or new entrants. The history of regulated utilities – electric, water, classic phones – is one of stagnation, and plenty of subtle abuses from those incumbents whose margins get effectively written into law.
