You can do one thing to reduce your viral load. Wear a mask. N95 will do better than a surgical mask. But even mask wearing seems controversial. These things are really hard to study so you need to err on the side of caution.
If the price of soybean, or wheat, or pork goes up 15% internationally as a result of US supply disruptions, that doesn't starve any Americans, but it absolutely causes deaths in Yemen, which is already in the middle of a famine.
I think your concern is real and well placed. When the economy is frozen for a pandemic, you have a demand shock and a supply shock, what happens to prices? I think this was genuinely unclear early in the pandemic. Interesting additional details here [4,5]

How about -- what's the max viral load one can sustain for it not to pass the 1st layer immune system? Is there really a 1st and 2nd layer? Can I resist it without getting antibodies? How much more effective is a KN95 / N95 mask in terms of viral load vs the others?
And why don't we have more high powered venting fans and permanent outside events and require building to open their windows or remove their walls in climates where that'd work?
