Sure, but this site also has a lot of people who decry industries who lobby for government regulation in their own self-interest. When it comes to wireline ISP's, net neutrality proponents can justify regulation on the basis of local monopolies, etc. But in the U.S., over 200 million people have at least three options for 4G LTE service. And Sprint already covers 35 million people with LTE and is growing its footprint. You also have regional carriers like U.S. Cellular who have deployed LTE. And you have T-Mobile as the underdog player engaging in a real price/service war with the bigger competitors. Calling for regulation here is just calling for rules that favor one industry over another.
And it's not just cellular companies that are hurt by such regulation. I used to work at a startup developing wireless technology. If you legislate cellular wireless into a low-margin, "dumb pipe" business, then those companies will have less money/incentive for R&D, and you'll end up hurt companies like ours.
And by banning bundling, you're eliminating the opportunities for real innovation in the sector. One of the ripest opportunities in the music/movie streaming sector is figuring out how to deploy it in mobile networks in a bandwidth-effective way. Bandwidth, especially mobile bandwidth, doesn't rain down like mana from heaven. Someone has to build the cell towers, someone has to lay the fiber for the backhaul. What if your startup idea involves helping cellular wireless companies distribute media content more efficiently using their existing infrastructure? Your interpretation of net neutrality forecloses on those opportunities.
