I dare say, wood smoke has caused more cancer than asbestos ever did. [1]

And there are whole programs designed to reduce worldwide deaths from smoke, precisely because it is a major problem. It's something we're actively working on because it's so serious and plausibly fixable.
So what on earth are you trying to say?
wood burning stoves are absolutely required to be updated now with certified emissions stoves. all four wood burning stoves/fireplaces in our cabin had to be replaced before we could finalize the purchase. also it would have been considered uninsurable if the stoves were not updated to meet the new wood burning standards.
these weren’t like antique stoves either, if i’m remembering correctly they were new in like 2000ish.
honestly, the region of our cabin is noticeably more pleasant to be in since they started requiring this—when i used to go there as a kid, the air was just awful to breathe when everyone was using the previous gen wood burning fireplaces.
Your link is talking about indoor fires. Outdoor fire pits wouldn't concentrate the smoke in the living area. I have no idea what the total effect would be for outdoor fires, but it isnt' the same as the indoor burning biomass stoves
If the rate was high enough I bet we'd phase it out. Don't underestimate the importance of the size of the effect.
