You don't need this pipeline to produce 6 shows over a decade. Said another way, they almost certainly would not have bothered to build this system if the purpose was mainly to produce the shows you mention. The reason these systems exist is to enable the creation of hundreds or thousands of productions.
House of Cards, The Diplomat, Kaleidoscope, Lincoln Lawyer, The End of the Fucking World, etc etc
Those were just six examples. There are many more.
But OK yes, Netflix produces a lot of volume because that's also what its viewers want. Are you saying that's a bad thing?
Sometimes people get home from an exhausting stressful day at work and they just need to relax with some mindless entertainment. And that's OK. Not everything has to be art.
