Physical media died when games expanded beyond their capacity. Optical discs are physically fragile, they have a limited shelf life, they have to be reproduced by specialized equipment (not considering piracy here), they have to be physically transported to the customer, some regions are financially unviable (imagine the Helldivers 2 situation but with every game), and production has to end at some point. Having to set up a physical supplier also severely limits the ability of indie or solo developers to have any kind of success or even presence.

Physical media is obsolete, and people clamoring for its return are nostalgic for a world that doesn’t exist anymore.
