The first point is exactly what Comcast can do with their own video service that they can't do with a random video service. (They can do it with someone like Netflix with open content servers.)
If NN were structured such that a company like Netflix had to provide content servers for internal-to-network deployment or netflix customers would higher rate or lower performance for Netflix traffic, but Comcast had to charge the same rate and same standards for Netflix, Comcast's own video product, or any other third party to do this, I'd support it.
I don't particularly value the ability of a carrier to engage in bundling/commercial exploitation of the monopoly, but I do want providers free to engage in technical innovation to provide multiple 4K streams and gigabit access to customers at $50/mo, etc.
This is an even bigger deal when you start looking at other network technologies (wireless/cellular, some of the WISPs, etc.) than fiber to the home or HFC.
