- NN is not a cost regulation as far as I know. It's preventing companies from doing something, not requiring them to do anything extra.
Lack of competition, reduces choice
- These are the same thing and NN is not meant to be a solution to the lack of ISP competition. I think you're right that local regulations are the root case of that though. NN is meant to prevent reduced competition of services that rely on the internet, particularly those that require heavy data use. Would someone be able to start a Netflix today and compete with the media services owned by the ISPs?
Less than 3 ISPs
- Mobile service is not a replacement for home internet service. Even with tethering most households would go way over their mobile data caps if that's all they used.
ISPs will produce different packages
- This happens all over the world in places without NN. But since most of the major ISPs are also media companies in the US they simple zero-rate their own media. This has the same effect of reducing competition among online services.
