The two are not connected other than by the word "regulation". You can still have local governments not give ISPs local monopoly over laid cables, but you can also have net neutrality, which says that companies shouldn't be messing with the traffic that passes through their pipes. The two aren't mutually exclusive. Also, some have mentioned in other similar threads that sometimes the monopoly is (sort of) natural because no other ISP even wants to lay the cables in a certain area. I do believe that to be true, but I don't think it's "case closed," either. Many other countries have solved this issue by either mandating that whoever is laying the cables would then have to license them to competitors (which could also bring them their return on investment faster), or they could have a public-private partnership, where the government invests alongside the initial company that is laying the cables, to reduce its costs, and then similarly they license them to new competitors later on.
