The fact that whole game isn’t on the CD isn’t some conspiracy to deprive you of ownership. Putting it all on CD isn’t going to defeat an always online requirement. It’s solving a technical problem. Long term game ownership is a problem solved through legislation or piracy.

To what end? The reason games came on multiple disks back in the day is because Internet speeds were slow (if they were there at all.) it was way faster to load via disk, and companies couldn’t even count on users to have a stable Internet connection anyway.

That’s not true anymore. The only reason physical disks exist at all now is more out of tradition than anything practical.
