Dumb question: Why do people want fast lenses ??

No matter what lens (50mm, 105mm) I have on my D700, I'm very rarely at the largest aperture since the depth of field is soooo shallow.

I'm usually happiest around f5.6 minimum and up.

I mean, I've shot portraits (by mistake) at f2 and whilst the eyes have been in focus, the nose, or peak of a hat hasn't or the hair at the back of the head hasn't.

Sure, there are people out there who shoot in dark conditions, but then it's over to ISO to fix that.

What's the deal ?
