If our ancestors spent hours in the sun, that means - by definition - that sunlight is basic to our physiology. We're descended from the folks who thrived outside. The ones who didn't thrive outside are not our ancestors.
That we don't understand all the ways in which sunlight is basic to our physiology is a separate issue, but our current limited understanding certainly doesn't mean that our ancestral exposure to the sun is toxic ,and recent history is littered with examples of how "science has now concluded" is an early stage of what turns out to be terrible medical advice (DDT, smoking, lobotomies, innumerable pharma products, saturated fats... it's a long list).

Obv you get to decide what healthy skin means for you, and how much sunlight you think you need. Go for it 😉
I'm not trying to convince you about what to do; just pushing back on your general statements on what's healthy.
