One could argue that, but one would look like a moron without any proof, and with a lot of evidence showing the exact opposite.
Given the huge amount of evidence of transmission by cough droplets and the lack of evidence of even a single transmission out of millions by touching masks/surfaces, keeping droplets out of your mouth and nose is the only thing that helps and it definitely does more good than harm.
You're free to cherry-pick whatever data fits your prejudice if that makes you feel better.
However, I hope you understand that garbage in means garbage out, and if you feel desperate enough to grab onto garbage to try to rationalize your prejudice then you should seriously rethink what you're doing, because thinking ain't it.
> Anyway, the measures about quarantine you point out or only just in effect and have no bearing on the spread and then decline, without masks as seen from February/March.
I'm curious to see where you came up with that nonsense.
If you take a step back into reality and look at the facts, you'd eventually find out how Spain and Italy reigned in their daily death rates from 1k to single digits by enacting public health policies that included a mix of quarantines and mandatory masks.
