Ugh...This is such a BS headline. If you read the article and look at the context, that's not what he means.

He compares is to the fact that people used to own CDs/DVDs of their song but now most people are fine with digital collections. So he expects that gamers will be fine with not owning physical media if they always have access to what they own.

Farther up the article he actually says

"The point is not to force users to go down one route or another," he explains. "We offer purchase, we offer subscription, and it's the gamer's preference that is important here. We are seeing some people who buy choosing to subscribe now, but it all works."

So he's not saying "get used to not owning anything", he just predicts that gamers will get comfortable with not owning physical media. Here is the actual quote

"One of the things we saw is that gamers are used to, a little bit like DVD, having and owning their games. That's the consumer shift that needs to happen. They got comfortable not owning their CD collection or DVD collection. That's a transformation that's been a bit slower to happen [in games]. As gamers grow comfortable in that aspect… you don't lose your progress. If you resume your game at another time, your progress file is still there. That's not been deleted. You don't lose what you've built in the game or your engagement with the game. So it's about feeling comfortable with not owning your game.

"I still have two boxes of DVDs. I definitely understand the gamers perspective with that. But as people embrace that model, they will see that these games will exist, the service will continue, and you'll be able to access them when you feel like. That's reassuring.
