Besides, what you're talking about is completely irrelevant. There is no benefit to forcing a digital distribution system on gamers--outside of company exposure, outside of enticing them to spend more--there isn't any software benefit. There's little, if any, user benefit. The analogy is poor.
There's huge benefits for the developer. Digital distribution is pretty much the
primary reason why independent games can become so prolific. As a gamer, if we were restricted purely to boxed goods, our selection in games would be more limited. Things like Project Eternity, Wasteland 2, and Torment would probably not exist. We'd certainly have less influences from various game styles that even make their way up and into the "AAA" titles.
Digital distribution is a huge risk mitigation, and stating that those smaller developers shouldn't force their customers to accept that digital is the avenue for delivery is too restrictive towards them, in my opinion. Many of them would never have been able to realistically deliver their games without incurring significant amounts of additional debt in order to finance manufacturing and distribution.
