You're not going to run out of atmospheric oxygen, no matter how much you breathe. There is, for your purposes, an unlimited amount of it. That may make all your breaths meaningless. But when I'm meditating, or bicycling up a hill, or face-to-face with my lover, or watching the sunrise on a cold morning, my breath has plenty of meaning to me. Limiting the amount of oxygen I was allowed to use would not lend those more meaning; scarcity is not the same as meaning.
