I think you overestimate how "easy" piracy is for the average user. Netflix revenue keeps growing (and subscribers), despite the "crackdown" on password sharing that many predicted would cause massive cancellations.
You overestimate your view of piracy. The average person isn't curating libraries of lossless music collections and carefully re-encoding Anime dubs to match their sound system.
People are Googling for the hundreds of sites that will stream a feed of a DirecTV box somewhere showing an NFL game, or show grandma how to connect to the Plex server their cousin runs.
According to TFA piracy is also growing rapidly, so it's apparently easy enough.
You may be thinking of usenet, torrenting, seedboxes etc. when it comes to piracy, but there are also (ad supported) public web sites where you can watch almost any content, or IPTV providers where you can pay a yearly fee and watch most things streaming providers offer once set up.
They're completely inept at technology.
