Not sure why you're dismissing lab studies because measuring the filter on that exhaust is one good way to figure out what's going on. But okay, this virus is less well understood than pollution. Look at SARS is best we can do probably.https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3322931/ …
I thought a lot about this, and am happy to follow through the challenge. Are you touching the outside? Better it's outside the mask than on your face, obviously no? Touching the inside? Well, it's your germs and that's exactly what we are trying to protect the world from.

What is the scenario in which a no-mask situation is worse for the wearer than a mask scenario in the community? I cannot come up with realistic ones, and this is what I thought about most because that's a real argument against masks.

(Also you don't have to block at the virion size, it's expelled in the droplet which is considerably bigger. And since you note dose matters, it helps even if most of it is blocked)
