Unless you're making a very particular type of video, you likely want to capture aspects of the water's movement, color, sound, or interactions without much care about faithfully capturing a video of the literal ocean. The former part is a big portion of what turns a video of the ocean from not inherently being art to being as much of art as you make it so. Saying the only reason would be to share the literal ocean forces the art out, not in.
