This statement was made by Ubisoft's director of subscriptions, Phillipe Tremblay, who recently spoke to Gamesindustry.biz about the digital future and Ubisoft Plus specifically. Tremblay states that people eventually "got comfortable" with not owning their CD or DVD collections, and that a similar shift in attitude "needs to happen" in gamers.
I've never gotten comfortable with not owning CDs or DVDs. In fact, if I really really like a movie or album, I obtain a physical copy. If it's an independent artist, I'll even buy it directly from the record label.
And so far, I've been able to stream everything else when I just want to get my entertainment fix ¯\_(ツ)_/¯
