I can't really agree with you here since this isn't the same thing. If I have bought a game then it's mine - if I'm not careful it will get lost or be damaged. But it's mine. If I buy a downloadable game, it's still theirs - I'm just allowed access to it for a "foreseeable future".
If the one I bought my physical copy of a game from one day broke in to my apartment and took the game away, then we're talking about the same thing again. A game in working order being taken away by the one who sold it.
I know you came into this discussion thinking that you knew what you were talking about, but it only takes a second to look inside any video game disc you've bought for your console or PC to see that you do NOT own the game. You own a license to use the software. You cannot copy it. You cannot do what you please with it, but the rights holder can. Any game company can remove modes, take down their multiplayer servers, or generally make the game impossible to play. They're called EULAs and you should brush up on them.
