This- people are 'min-maxing' on single isolated dimensions, and not looking at the bigger picture. Sun does a lot more than increase vitamin D, it also increases metabolic rate by acting directly on the mitochondria, lowers blood pressure, calibrates the circadian rhythm, coordinates eye development, and many other vitally important things.... and it turns out the most of the most deadly types of skin cancer aren't even caused by sun exposure. When you unnaturally radically alter your diet, physical environment, or lifestyle to an extreme outside of normal human experience based on trying to optimize a single variable in attempt to be healthier, it is almost guaranteed to backfire.
