Devil's Advocate argument attempting to answer your 2nd question: Because the [total cost/user] value is much lower on streaming video. They can charge thousands-millions of customers a small amount to be able to stream the same sets of videos. A similar comparison would be a shared, public concert vs a private concert for your family alone. Those things have much different costs. I'm not saying that that's good or bad, but does that help you understand the argument?
