Your analogy would be better with fast food, ice cream or candy than with milk. Nobody needs Netflix and ironically the society would probably be better off if people did not waste so much time with their eyes glued to their screens.
I see your point but as long as it's services like Netflix I hope people will not claim it as a right.
I think you misunderstood the OP's post. He is saying that the people have a right to access the internet as a utility,
regardless of the destination address, be it Netflix or Google. Just like I should have the right to choose which food I eat, be it milk, or as you suggest, candy or fast food.
Netflix in particular is indeed not a right, and in fact Netflix charges a monthly subscription that you may or may not be able to afford. But if I pay for Netflix, I should have a right to access it, or any service I want, via my "chosen" internet service provider.
Anyway I'm making this post because I think I have a better version of the milk analogy, so here goes...
The main problem with the milk analogy is how the transactions are done. I pay the grocery store a fee for access to walk in and out of the market with a certain weight of groceries per second. Separately I pay the milk provider for all-you-can-drink access to milk.
(Alternatively, you can imagine the grocery store is one of those stores in a mall that you have to walk through to get to the rest of the mall, but I'm forced to walk in and out through their front door).
In this analogy, the grocery store should have no right to limit the amount of milk I can carry through their market, while claiming to offer access to any food by weight.
I see your point but as long as it's services like Netflix I hope people will not claim it as a right.
