If they want to screw you over they will, they still control the full software stack. If you make a backup of the game you downloaded that might also simply not be allowed back on the machine, at least in theory.
What makes you think Sony/publishers will take away your games in some way that they don’t already without physical media?













In most jurisdictions you are always just buying a license, physical media or not. Except now you have a physical thing that you need to protect from damage/loss because it’s tied to your license. Depending on where you are you might not even be legally allowed to create a backup, especially if there’s DRM involved.
The only advantage I see with physical media is the used market. Digital kills that, and I’m sure that that’s the big reason Sony is doing it. They don’t want to take your games, they want to stop you from buying someone else’s.
