I don't know that we can say this. We each look at the world through a particular perspective, but there's no necessity forcing us to say that we're the only one looking at the world through that perspective. I don't even think there's a necessity forcing us to identify with whoever was looking at the world from that perspective a moment ago, because memory is part of the body. We could be an infinite number of consciousnesses superimposed upon each other, blinking in and out in an instant. Consciousness could be a quality of every point in existence, but it only sees itself as a consciousness during the instant that stationary point is being passed through by a moving human body.
A current point-of-view doesn't require a lot of things you'd expect out of individuality. Not that I necessarily think that this must be how everything works, but if it isn't required in order to explain the subjective experience of self, why not use Occam's Razor?
