It sounds like you're saying that if there's any video you'd like to see that's not available on Netflix, you have no alternative to pirating it.
What would be the fallout if you didn't pirate those videos?
A streaming service is attractive when the monthly cost is less than what you would pay for the seperate content you actually watch, and if all the content you want is offered on that service. Needing to subscribe to multiple services can quickly balloon the cost and inconvencience to the point where it's easier and cheaper to just seek out individual content - either legally or illegally, the result is the same for Netflix.
TL;DR: I'm curious if there's a way to make effective ethical arguments when people have fundamentally different world views, including whether or not morals have any solid grounding.
If nobody pirated anything then we would still be buying music for 99 cents a track (or more) and music streaming would have been quashed by the labels.
On the other hand if everybody pirated everything then the music industry would have collapsed.
I conclude that the world needs all sorts of people.
