>Cloth and surgical masks do not work.

this sort of statement really bugs me.

anything that slows the airspeed/spread is helpful. and there for "works". A cloth mask is definitely better than no mask... its has a much higher chance of catching larger droplets than no mask, it has a much higher chance of rate limiting even smaller droplets than no mask.

if 100% of the population worse cloth masks you would get a significant reduction of spread just because of the rate limiting.

N95 masks are not 100% effective.. so do we claim that they "Dont Work" as well? no we dont.

Nothing is black and white. nothing is works or doesn't work... every little step on the way every little effort all helps and by extension "Works".

Your argument, like many people made at the time this started, is purely technical. It only considers the virus itself to be the thing needing to be solved, rather than considering second-order effects.
If we banned all access to beaches, that would be helpful and "work" to reduce the number of people who get killed by sharks. If we should mandate cloth masks, then why shouldn't we do that too?
