i agree that mandatory downloads are a big problem (thats why willitplay is a thing) but offline installs from disk are the biggest change that made ps5 games load so much faster than ps4 and opened up a lot of new options for devs. reading data from ssd will always be faster than a blu ray. the only downside is you have to manage space a bit more but its worth it. if you want straight from disk get ready for slower uglier harder to develop games.
You can occasionally get one where a very final version copies straight off a PS5 disc.
