Allowing market forces to work solves the original problem, and does not create laws limiting freedom and innovation in the company.
Service providers should not be allowed to use local monopolies to harm competition in other markets or to form cartels in them, but legislated "neutrality" doesn't seem like the right way to ensure that.
You're free to get a leased line that is private and just yours, but you will pay significantly more for that. The Internet lends itself so obviously to packetization and shared wires that it takes an extreme case to justify using a private network rather than sharing a public one.
There needs to be regulation to stop (say) the DSL company from impacting VOIP traffic. But a completely unregulated network will lead to the torrenters destroying the VOIP traffic just as fast.
Maybe we should do what they did in the UK, and require the owners of the physical layer to the homes to lease lines and space in their switching centers at a reasonable price to independent ISPs. Then there would actually be a competitive market for ISPs, and then we could let market forces provide net neutrality for those who want a neutral ISP.
