In the emerging countries like Indonesia, the optical disc usage is still pretty high. The internet speed is the main culprit here. I took me days and nights to download a 10GB game from Steam for example, whereas I can go to the mall/shop, buy physical disc of the game, and go home. All in an hour. Btw it's even easier to buy pirated one here. The pirated games sellers are literally everywhere, both in physical and online shop at mere $0.4 per DVD!! Also, not everyone has unlimited internet bandwith quote, so downloading big files from internet can deeply wound your pocket. It's hard to justify throwing the optical disc altogether when it's still provide content faster and cheaper than digital (streaming/downloading) over here.
