Last week we learned there is plausibly a simple, cheap and easy way out of this entire mess. All we have to do is take our Vitamin D.

Taking vitamin D supplements can help, if you are deficient, but it is not a cure.
There is no “simple, cheap and easy way out of this entire mess”.
Excerpt:
To protect himself from COVID-19, Dr. Anthony Fauci has long said he’s skipping hugs and handshakes, wearing a mask, and staying off of planes. Last week, he acknowledged adding another step to protect his health: taking supplements of vitamin-D.
“If you are deficient in Vitamin-D, that does have an impact on your susceptibility to infection,” Fauci, head of the National Institute of Allergy and Infectious Diseases, said in an interview posted on Instagram last week. “So I would not mind recommending—and I do it myself—taking vitamin-D supplements.”
However, while spurious claims that vitamin-D can prevent or treat COVID-19 have proliferated online, including some recommending potentially dangerous doses, it’s important to point out that Fauci wasn’t talking about vitamin-D helping with COVID-19 in particular. Instead, he was speaking more broadly about vitamin-D’s importance in caring for our immune system. (...)
How should people think about their vitamin-D intake during the pandemic? For starters, don’t view it as a silver bullet protecting you from COVID-19—there’s simply not enough scientific evidence for that. But if you’re one of the many Americans with insufficient vitamin-D levels, it may be a good idea to increase your intake—if not to protect yourself from the virus directly, then at least to improve your health more broadly.
The author discusses impossibly perverse behaviors such as blowing up one’s island, but forgets to mention the most common anti-competitive practices such as dumping and product tying.
For example, the other guy would price coconuts and bananas well below the Zone of Possible Agreement (dumping), and you would be so glad to buy everything from them—destroying your industry and increasing his comparative advantage.
Of course, he is not altruist, so, when you are completely dependent, he will raise his prices above the ZOPA—and you have no option because it would cost you a lot (time and effort) to rebuild your industry and regain your comparative advantage.
If you try to produce bananas, he drops the price of bananas, making profit from coconuts; if you try to produce coconuts, he drops the price of coconuts, making profit from bananas.
When you start to recover one industry (say, coconuts) he could force you to buy coconuts if you want to buy bananas (tying).
And if you ever managed to rebuild both industries, all he had to do was to bring his prices below ZOPA—and you would have to decide if you still believe in free and unregulated markets, or avoid the same mistake, imposing tariffs and regulation.

You can observe this kind of imbalance in the real world: developing countries export iron for $100 per metric ton ($0.05/pound) and buy high value-added products (phones, tablets, computers) for $500/unit.
Developed countries use the profit they make from high value-added products and services to subsidize their farmers, pushing the price down. For instance, wheat costs $188.75/ton ($0.10 per pound).
Without subsidies, the farming industry would be decimated from rich countries, and prices would go up. Of course, there is no such thing as “free market”.
Markets need regulation to prevent anticompetitive behavior.
