And when they disable the download because “game is old” or “we want to remake it” or “servers are too expensive” then what?

You don’t own the game and you don’t sell the game. You own a temporary license to play the game and sell that license.

Just like on Steam or any digital store front.

Sure the advantage is that you can resell your license, but let’s see if those cards still do anything in thirty years, like games from thirty years ago do now.

They made a really shitty situation (not owning your games) a little less shitty.

p.s.

Obviously we are also in this mess because convenience trumps ownership, that’s why Steam and business models like these grew so popular.
