People do it all the time already and it's not limited to games. Books, music, movies...
I wish people would have been more vocal about this earlier, but I guess better late than never.
The fact is that not everyone is affected by this DRM stuff.
Not everyone is a collector. Not everyone replays games or rewatches movies or rereads books.
I love my Kindle and read a ton more because of it. The books are cheaper than paper books (some aren't and I just don't buy those). I don't get stuck with a paper copy I will probably never re-read and just end up donating before I move (I don't plan on ever staying in one place permanently) and it's much better than hassling with library waitlists and due dates etc.
The books are DRM'd, but I don't care. I can read them on my Kindle or Kindle software on my phone, iPad or any of my computers. I'm pretty confident Amazon will never go under. And if they did there's software that can strip the DRM. But it's pretty moot as I pretty much never re-read anything anyway so I don't really care about the remote possiblity of losing my e-book collection.
It's all about the convenience of digital goods for me--with the BIG caveat that I expect them to cost less than their physical counterparts. I won't pay the same or more for an e-book than the cheapest print version on Amazon, I won't pay the same or more for an mp3 album as the CD, and I generally won't pay the same or more for a digital game as the physical one (making an exception for the 3DS Animal Crossing as it's a play here and the game and I don't want to be switching game cards all the time just to check on my town for a few minutes).
It does suck for people who like to collect physical goods as a hobby. Who want to make sure they really own the things they buy and can enjoy them for years and years to come as they like revisting things. And I feel for those types as the move to a digital media world will be very painful for them. And I get that the other media are different as collectors can (at least for the foreseeable future) still buy Blurays/DVDs, CDs, and paperbooks, and with Xbone even the discs are DRMd and basically just another way to transport the data to the console other than downloading huge files.
But that doesn't make those of us who like digital goods blind or naive about DRM etc. It's just that for us we see far more benefit than harm as we're not collectors, don't care about permanent access etc. I'm probably more extreme than most on that latter point as I'd prefer a world of digital rentals/streams for everything. Put every game, movie, album, book on cloud/streaming services and I'd happily stop buying and just spend up to a couple hundred a month in subscription fees for instant access to any game I wanted to play, movie I wanted to watch, book I wanted to read, song/album I wanted to listen to etc.
That's probably a pipe dream for my lifetime in terms of complete coverage of all content, internet capacity to handle it etc. But I'd love it as I love instant gratification and I hate being smothered by physical possessions beyond the essential furniture, clothing, TV set up, kitchen stuff etc. as I want to be able to drop everything and move for a new job in a new city or country at the drop of a hat and not turn down things due to hassle of moving everything etc.
So for some, digital goods just have clear benefits and fit our lifestyles better. Again I note the big caveat of pricing as I won't pay the same or more for digital goods. So MS and publishers can piss off if they are expecting $60 for new games that are digital or DRMd and can't be resold, with slower price drops etc. If it was a steam pricing model, I'd be there for sure. But I doubt we'll see that this gen unless it really bombs out of the gate and has to make major changes.
