This is so wrong. One has to really wonder what motivates you. Mask wearing alone, a simple action, dramatically lowers predicted infection rates
A Danish clinical trial enrolling 3000 people will probably give some more concrete answers.
OTOH, hand washing and distance are definitely useful to reduce spread.
P.S. Feel free to state your disagreement explicitly instead of downvoting.

Of course,I agree that absence of evidence is not evidence of absence. But, as the BMJ post I quoted earlier says, instead of just saying "wear a mask", the best idea would also promote trials to verify their effectiveness (like the Danish trial). It's done all the time for drugs, why not masks?

"missing the compounding effect" - What about the compounding effect of numerous people putting a plague vector directly on their respiratory system?
"Mistaking Absence of Evidence for Evidence of Absence" - The argument isn't that because there's no evidence it's guaranteed to not work. The argument is that without solid evidence constitutional rights should not be infringed.
And on and on.
It will do something, in a very complicated way, but compared to things that really matter that we haven't been able to push like mask wearing(you disagree) and social distancing and being outside, hand washing has been a huge distraction, which is the same as saying it's helped increase the spread.
