This ignores the underlying issue this post was about. Games being sold on physical media will likely last longer than games sold as digital downloads.
If you store a professionally pressed optical disc in an environment with good temperature control and low humidity, it may last 50 - 100 years. Only about 10% of pressed optical discs fail in under 25 years. Meanwhile, companies like Sony will take down their storefronts with little to no thought.
Yes, for backups, you're better off storing bin/cue files than trusting a cheap burned disc that will only last 1-5 years. But games getting sold with physical disc gives people the ability to rip them.
