If Pai is truly a believer in free market and competition, then don't stop at just knocking down net neutrality. Remove the regional monopolies that restrict where existing ISP's can and cannot do business. Remove roadblocks to cities building municipal fiber, since this only creates more competition so long as they're on a level playing field with private ISP's. Lift restrictions on last mile unbundling so that more companies can enter the market and offer competing services.
The fact is net neutrality was such a necessity only because there are few players in the market and limited choice for consumers. Who cares if ISP's can create fast lanes and throttle non-partnered content if I have a list of 20 ISP's with broadband speeds to choose from, since there will always be those whose model is to offer a more open package, even if it is at a higher price. The ISP's are crying about regulation, but only when it's regulations on what they can do. Once you talk about remove regulations on what their competitors can do, suddenly these restrictions need to be upheld. Because if you gave the average Comcast customer the option to choose another ISP with better customer service, no data caps, and more transparent billing practices they'd take it in a heartbeat, even if meant an increase in monthly price.
If Pai truly walks his talk and heavily deregulates the industry by removing barriers to entry and regional monopolies in addition to net neutrality, he'll be a far better FCC Commissioner than Wheeler ever was. If however he's yet another industry talking head who's only interested in removing consumer protections while still leaving in place industry friendly regulation, then nothing good will come from his chairmanship.
