You can BUY a license to something, but it's still a license. You don't own the actual game unless you buy the rights to it from the publisher. The rights to a game can cost millions, and only then, do you truly, ever own it.
When I buy a game disc, I own that copy of the game on it. I can give it away. I can sell it. I own that copy, in the same way I own that book. No own claims to "license" a book anymore, or at least no one who doesn't get laughed out of court.
Take away the physical medium and there is nothing physical left that you own. Therefore, you have no physical rights to it anymore. The publisher, at their sole discretion, can remove the medium of access by which you consume the book. And then you'll be left without a book.
This is exactly how the current system works, I am just explaining it to you. So don't shout at the wind.
When you own a book, you own that copy of it. You can do whatever you like with that copy, short of distributing copies of it. You can sell it. You can lend it to friends. You can leave it laying around a doctor's office for a stream of people to read. Short of distributing copies of it, it's yours.
Sony claims you do not own your copy of a game, merely the right to use it until they decide otherwise. That is fundamentally different than when buying a book, or CD, or DVD.
The fact that some of the material exists in a form that is close to and within your control is irrelevant. That's like saying you own a copy of Google because some of the javascript code that runs the frontend is cached in your web browser. You don't.
"You will own nothing and be happy." better get used to that and make your peace with it
