From an outsiders perspective, the last mile in unfeeling is the only bit that matters, market forces can resolve everything else, but it's not really possible to lay a dozen sets of last mile infrastructure.
Last mile unbundling isn't about neutrality though, it's about getting better service. If one wants to advocate for that, it should be decoupled from net neutrality. Net neutrality is about preventing fast lanes, charging companies for access to the network, and degrading competitors products.
