Its not so simple. NN is not political, its commercial, and partly technical. One main sticking point is that ISPs don't want to pay for asymmetric peering. If you're sending more traffic on my network and I'm sending you almost none, I need to have larger 'pipes' to accommodate your traffic, but you don't, for my outgoing traffic. So, If peering were 'settlement free', as Netflix wants, that is beneficial for Netflix but not for Comcast. Also, any network, already has several routes for any given packet. By default, you HAVE to do some prioritization. Traffic internal to the ISP will always be prioritized. So if I were an ISP and I became a content provider, obviously my packets will be "cheaper/faster" to route than incoming NetFlix/Hulu, etc etc. The above is just a supersuper simplified summary of some points off the top of my head. There are tons of nuances, which are more suitable for a detailed blog post, and not a comment. I'm sure someone has done that already.
