You know, you almost make sense, and yet: "No, it doesn't matter if it makes sense to anyone. Let me explain. If I come up with a design for something that works on paper, but not in real life, then it doesn't matter."
In essence, you just said that it does not matter what makes sense, and then refuted it by saying it does matter. In order for us to know that something 'on paper' doesn't actually work, it must be tried in real life. It is at the point of failure that it suddenly 'makes sense', and leads us to return to the drawing board to start over. When you reject the concept of absolute truth, you always find yourself running in circles. Always.
As for the study, there are others which show the contrary, as does the last 50+ years of actual mask use. Masks were not suddenly discovered in 2020, but their misuse was. And if you have not been paying attention, then you would have missed both the CDC's and Fauxci's constant flip-flops on the matter, flip-flops no doubt directed by political motivations, certainly not the "science".
