TBH, 100% offline gaming has been problematic since day-one patches became the norm in the PS3 era. Sure, you might be play version 1.0 of the game from the disc, but often the experience was pretty compromised without the patch, often very buggy, or sometimes even features missing.

And the PS5 is meant to be able to play digitally downloaded while disconnected (at least the ones you own, not the PS+ games). It's just the implementation is little buggy, it sometimes breaks for some people and you get a bunch of vocal people complaining about how it doesn't work.

So IMO, you aren't losing much there. The digital-only experience isn't that different from needing to have internet to download a day-one patch.

It's the used game sales that are the biggest loss from this move.

I remember getting some Gran Turismo game for my PS3 back in the day, having to wait for it to slowly copy XX gigabytes of data to the hard drive, then being stupid enough to want to start the game while being online which meant having to download once more the exact same number of gigabytes (hello, incremental patches?) over an even slower Wi-Fi connection. I bought the game on a Saturday afternoon and was looking forward to it, but by the time I got to play it, it was Sunday.

So I figured that the last console with which I really felt like I had a collection of games that were mine, that I got to keep and could play whenever I wanted, was the PS2.
