Of course this quote was from a different time. It's still true in a sense though. Patches won't always be available.
To a lot of people it won't matter. If patches are released within about a month of the game, most players will get those benefits and not give it a second thought.
But the patches won't be available immediately or forever. So you have these other groups of people, the ones who play the game many years after release, and the ones who go through the game quickly before a patch has been released (excluding day 1 patches though, those still work for this latter group) that don't benefit from the patches. What's on the disc/cart is still important.
