It claims a link between sunlight exposure and lower death rates (which I can buy), and claims vitamin D is "just a marker [of exposure]".
It also discusses studies that show vitamin D supplements don't change life expectancy.
But it jumps from this to "don't use sunscreen" which is a dangerous jump, completely unsupported by anything discussed in the article.
They have a correlation between low levels of sunlight exposure and higher death rate. They know it isn't shortage of vitamin D that causes that. But they don't know if sunscreen stops whatever it is that reduced the death rate.
As a random hypothesis: we know sunlight reduces depression[1], and that depressed people have lower life expectancy. The mechanism there is serotonin production, which isn't blocked by sunscreen.
I'm not claiming that's the answer - I'm just pointing out that there are many alternative explanations and the evidence for the dangerous advice he is giving ("don't use sunscreen") is missing.
