Yeah, but many modern games only work after a day 1 patch anyway, so what’s on the disc won’t count for much. Not to mention you still need a working console, and those stop being sold long before digital storefronts are closed.
I don’t think DRM free is realistic either, piracy is just too big of a problem on the release of a new game. Eventually the cracks will arrive, but that window before is important for making a profit. Most consumers are as amoral as corporations. They don’t care about who makes what they are using, nor do they care about the ethics behind where they got it from.
