Yep masks work. They exist for a reason. Kinda like how surgical masks exist to keep the surgeon from spitting into the area that he is operating. Essentially to limit bacterial spread. Not to limit viral infections. And with cloth masks, you're talking about a non medical device all together. Facial coverings of that type have essentially just been used to limit the inhalation of dust/sand. Do they do some good? I have no doubt. But the needed scientific research really isn't there to describe the situations we're talking about.
It's quite simple. Face coverings stop what you exhale from dispersing as far and masks rated to filter out particles the size of covid-19 do indeed work and filter out those particles. Plus, like you mentioned, people wear masks for dust/sand and they also wear them for allergies or for chemicals/gasses/fumes. I don't see why people would claim "they don't work".
You can't just say "masks work". Work for what purpose and to what degree? To avoid specifics is to avoid the problem we currently face, which is that we simply do not have a robust body of research around the efficacy of the different types of face coverings in different situations.
No, you aren't being specific. What is the efficacy of a cloth face covering in a retail setting in terms of lowering transmission rates? You don't know, because the research isn't there to tell you with any sort of accuracy. "It just works" isn't solid ground for macro level policy, and sure isn't a proper basis for a lot of the sweeping declarations we are seeing in society right now.

Care to elaborate on what you meant or are you just trying to fit in with the other crickets?
Your username, seperatedFromReality, accurately reflects you mental stat with regard mask wearing.

To be specific, cloth coverings stop the particles you exhale to disperse as far and filter out a little bit of the larger particles.
Those blue strap on doctor's masks stop some larger particles and some bacteria along with a little bit of the larger virus particles.
Allergy masks stop the larger allergen particles.
Respirators and N95 rated masks stop chemicals, gasses, pesticides and the smaller virii particles.
Full face gas masks stop 99.9% of airborne particles, gasses, chemicals, etc ...
So yeah, masks do "just work". They are designed for a reason. If they didn't do anything at all they wouldn't exist. Sort of like walls.
