Because if the game isn't for me I can sell it. I can share them with friends easily. I can install and play a game if my network has issues. I can buy games way cheaper than the insane PS store prices as there is actual competition in physical media sales.

Because without physical games there is no secondhand market. If the only place you can buy PlayStation games is Sony's digital only store, they have no incentive to lower prices and can revoke access whenever they want.

1. I like to borrow game disks from my friends.
2. Sony will delete digital purchases from customer devices and not compensate the customers. Other companies have done it, but Sony seems to do it more often than anyone.

We have sellers like Amazon removing items from their store, which are then fully unavailable to the consumer. They also allow people who have shit internet to be able to play games. I knew someone in college who tried installing Terraria and got an ETA of ~12 hours.

Lots of people are also mad about DRM, it's just also an older argument, so less new. Also with physical media DRM will inevitably be cracked, so it's less of a forever barrier than not being able to own the game on disc.

It also affects people who don't care about DRM. Collectors can't get games for their shelf anymore. You can't sell a game you've played to get back some of the cash. You can't tell friends to look at your shelf to see what games you have, which isn't that bad with one console, but if you have all 3 of the major ones you suddenly have to boot up 3 consoles instead of looking at one shelf.

Also, just human psychology: We hate change. DRM has been in games for longer than a lot of gamers have been alive, discs disappearing just happened.

Because not everyone has good internet. It took me nearly a month to download Doom 2013.

I have a feeling you haven't been without power or internet for a few weeks. I have. What do you do in that time? I played my 3ds, that I charged with a mini solar panel, it kept me sane while eating mre's and canned goods in candle light in hot ass heat.

If you don't have a physical copy (without online DRM) then you do not even own it. You purchased a lease with an unknown expiration for the full price of a game.
