Because brick and mortar retail isn't entirely dead. Impulse buys, Christmas gifts, etc etc etc etc. All the reasons to have a product for sale in a store. The product was never the CD or DVD or floppy disks, and gamers who make a fuss about it are just crotchety for the sake of it. There's no reason to print physical media. I haven't even owned an optical drive in my pc for well over a decade. Still bought some "physical copies" of games that were just codes. I'm not upset.
You're old grandpa, go back inside and stop yelling at The Cloud.
