"There is no evidence" means only that, it doesn't mean we shouldn't wear masks to prevent community transmission. You can still use logic. It's a virus where transmission is heavily influenced by water droplets. Masks limit the reach of water droplets from the nose and mouth. Also it is unlikely for there to be a large study for ethical reasons (if wearing a mask might help, you can't get a control group). > it at a minimum establishes the very real risks of cloth mask wearing That is a pretty gross misreading of a study which has no non-mask control group and looked very different conditions to the pandemic
