Owning a game is more like owning a book or movie. You own, essentially, a token of access to a narrative. Even a digital book is only available so long as the platform providing access is maintained, and physical media not being properly maintained doesn't entitle you to new methods of access.
Add on top of that the unique legal situation surrounding ownership of code and owning a game is something you could realize was never possible.
In fact, we never have owned a game. As much as you've never owned your browser or any software you didn't write yourself outside of IT work hours or a much as you've never owned the story telling of a book or movie. Buying a game never entitled you to that game being functional and accessible to you into perpetuity, even if we didn't realize it while we were young.
I'm all for game preservation efforts, but "try again next time, here's what you could do better" isn't a shattering set back in my opinion
