I think the reason people obsess over physical copies is because of a small sense of nostalgia.
Nostalgia of back in the ol' days when you had to go outside and buy games in person at a shop then come back home to open up the box and put it into the console. When you didn't have to just sit in front of a screen and plug in your credit card number for 5 minutes. Nostalgia is great, everyone loves memories of doing fun stuff as a kid but I think the people that obsess over physical copies just try way too hard to keep holding on to that nostalgic feeling.
