Also one of the reasons that I won't buy digital if there is physical available. I've never been burned like this, but I understand that when you are making a digital purchase, you don't own the game, you only own a license -- which can be taken away at any time. Plus, you're relying on the service still being around in the future. Does anyone remember Desura? All those Free Plus games and other digital purchases amount to nothing if Sony ever decides PS4 is no longer relevant or discontinues Plus. Twenty years later, I can still put an NES cartridge into NES and play it. Will I be able to download and play that free Plus game I got a few months ago twenty years from now?
I buy physical, not digital unless it's a digital only release, for collection, resale, feel of ownership or whatever reason. However, I do think digital has its own advantage. You have your point but you haven't considered all situation.
What if you NES cartridge or system was broken one day? If your NES system was broken, you couldn't play any of them and you cartridges are no more than paperweights.
Electronic can fail any time, cartridge, disc reader will wear out or destroyed by accident or any physical means, so they will certainly not working one day.
However, I can still play the NES because I have the NES emulators and the ROM files on PC which will work on any old PC and probably next 10+ years PC. That you can consider its the digital version.
Digital game is more like an ownership right. How long it will last depends on how Sony or the company want to do it. They can be a-hole or they can keep transferring your right to the new platform, by means of hardware backward support or using emulators like playing PSX games on PS Now and etc. That can potentially last longer than a physical cartridge or disc.
