Your argument has no basis in reality. What you have failed to understand that as an ISP the companies have a right to give service as the see fit. There is literally no reason as to why Comcast should treat Youtube, Netflix, NBC, and whoever else the same. Even if there are no cost differences in terms of the networking side there are still other considerations to make when it comes to net neutrality. Thus the idea of treating such data equally is laughable at best and sad at worst. The true genius of the net neutrality movement is that it is being led by in large by massive corporations (Google, NBC, Disney, and whoever else) that have a large impact on terms of how it will affect them while targeting some everyday joes into supporting such legislation on the grounds of buzz words that are ultimately attractive to the same crowd who have no clue what it is about.
I am just going to say that I respect you, but you are kind wrong on this one
First, you argued that ISPs are hurt by services like Netflix and Youtube, expect they aren't. ISPs put a data cap on your service, thus meaning they've already determined how much data you can use before it starts effecting them. This means you've already gotten a set amount of data to do anything you want with, so long as it doesn't go above that cap. Thus every service you use, they've already calculated into your bill.
Second, your idea that they have the right to tell you what you can and can't do is simply wrong. That would be like me walking into Subway, ordering a tuna sub, and them telling me that I am getting ham because it's their store. ISPs are a service provider, they are a customer service company like every other company. They should not have the power to determine what you can and can't do, so long as it's within the law.
Finally, you keep ignoring the issues with censorship. Without NN, ISPs will have the power to determine who gets the best speeds and who doesn't. This isn't just limited to sites like Youtube, this includes the entire internet. If Comcast (for example) decides they don't like the content on GBATemp, they can legally slow it down. From there they have the power to decide what happens, they can demand the site completely strip itself of hacking related content, they demand the staff/users to pay a higher fee to access that site at full speed, or they can simply lag the site death. Without NN, the ISP has all the power over what you can see.
And if you don't think they will try to starve out a service, realize they've already tried to do it before
