Never too many, never enough
If you by some weird logic or another to ask me if one could have too many pinhole images of the ocean, or even the Oregon coast specifically, I would probably answer with a question like; can the ocean have too many waves? Or can light fall on a sheer cliff too many times? Or can sand rearrange itself into hypnotic patterns often enough? Your answer to those would most likely match my answer to yours.
