Disc > Steam > Digital console

Steam games exist on physical media that players have some control over: I can copy my Steam data directory across PCs/Steam Deck, I would not be able to do that on a PlayStation.

Sure, I can't resell my Steam games, but the openness of the PC platform has advantages over closed consoles. Valve can't brick old games the way Sony can - a new computer in 2046 will be able to play single-player games backed-up from Steam, not so much for consoles.
