"Imagine enjoying a court side seat at a game, studying in a classroom of students and teachers all over the world or consulting with a doctor face-to-face — just by putting on goggles in your home."
You could always go to an actual game, and then truly be part of it and have a unique view of it, rather than an identical one to you and the hundreds others using their Rift. If you're not personally experiencing this then surely it's just like watching a game on TV.
You could always study with students and teachers from all over the world on a computer. Whether with the Rift or not you're still not actually in a classroom and won't experience the touch and feel of that place.
And why would you want to consult with a doctor via an Oculus Rift? They can't see you and they can do zero examinations on your person. That is why people go to the Doctor's after all. To be checked over and treated for physical problems. They don't go there just for a chat.
The Oculus Rift has some great applications, such as Games, Movies and Theatre, but some of these suggestions just seem pointless and unnecessarily void of physical contact/presence.
