Back when Netflix first started, and they were sending out DVDs instead of doing streaming, my stepdad, who is now in his mid-80s wanted to get his money worth. So, he started ripping the movies immediately and returning them the same day, ordering more as quickly as he could. When I went to visit he'd always have added more to his bookcases of DVDs. He recently setup a NAS and Plex and copied them all over. They, my parents, have a streaming service, but they live in the boonies so the connection isn't great, and having thousands of movies and shows ready to go is great for them.
Some old people know a thing or two.
