I miss physical media as much as anyone but there is really no point in a physical release.

I bought GTA V PC on disc because I had slow internet. There were 5 discs and 2 of the brand-new sealed package discs wouldn't read. I spent half the night polishing the discs with toothpaste and finally got the install to succeed. And then the first time I launched it, it required downloading huge update files before it would let me play. That took many more hours.
