My point is that owning games was never any good because there was always some severe limitation on your legal rights since the game itself is a piece of software and there's no universal way to guarantee your ownership of a piece of software.
The disk could always break. If there was any online component, they could always take down the servers. Or if the game was broken from the start or became broken at any point, they could always just never provide the necessary update to make it playable.
I've never really been one to sell my games because I'm always wanting to go back and play them later, so I can't really offer any input on that fact.
I just prefer the system that gives me at least a paper thin guarantee over the one that's less convenient and has absolutely no guarantee.
At least it's digital rights control now instead of your rights depending on a fragile piece of plastic and aluminum.
What good is legally owning a game if I lose access to it just because it physically broke? I'd still have to buy it again (or pirate it) if anything happened to the disk, so IMO, it's a wash.
We give up legal rights in exchange for extra short term safety and convenience. And if Steam or the developer ever takes it away from me, I can always just go pirate it to get it back.
