Quite right, I didn't phrase that well.
Of course, even if unhealthy sun exposure + sunscreen is better than unhealthy sun exposure on its own, it doesn't mean it's better than avoiding the unhealthy sun exposure patterns at all.
I feel like there's a fair bit more to figure out here. A lot of us live far from the equator with jobs and hobbies that keep us indoors a lot. Observing that regular safe sun exposure is healthy is great, but I don't even like beaches. It's easy to criticise bad ideas (vitamin D supplements, tanning beds, etc.) but harder to figure out the best compromise.
Agreed but Sunscreen might still be better in that case. See point 4 (Intermittent extreme sun exposure (the kind that causes sunburn) actually is terrible). These people would be sure to get bad sunburn if they lay on the beach all day only 2 weeks out of the year.
