But Netflix's value is not from competing against cable on price, it's competing against piracy on convenience.
Content providers will never again see the same profits, because the de-facto price of content is zero. It's too easy to pirate, and morally grey enough that people are willing to do it.
Netflix got so big because it captured the market of people who were willing to pay for the convenience. If this gets too high they will just go back to pirating.
