First off you seem to be a little muddled on your thinking that masks don't help. It could be because you have no idea how some infectious diseases spread including Covid-19. Do they stop everything - of course no. But they are certainly better than nothing and the better quality mask the better protection. This is rather simple logical reasoning that does not require much IQ to figure out.
As for the rest of your illogic about gain of function research - when the credible sources come up with evidence then I'll have an opinion. Right now you're tilting at windmills.
