In conclusion, I agree that constant, ubiquitous mask wearing does not make sense in almost all outdoor settings, but they are absolutely critical in nearly all indoor spaces. This is unless the space is some large, cavernous, uncrowded space, and/or you are there for a brief period, and/or it is a very well-ventilated space. But making rules for each space would be far too complicated, and dangerous mistakes would inevitably be made. Thus, it is best to err on the side of safety and wear your masks indoors, people .
I hope this helps clear up some of the questions and confusion triggered by these recent trials suggesting that “masks don’t work”. They absolutely do, and are critical to protect yourself. You just need to understand which mask and in what situations.
