Actually the idea is not off base, and in certain contexts it is way more important than wearing masks in public, and the data backs up that statement.
When do most Covid-19 infections occur? They occur (a) in close contact, (b) indoors, (c) with continued contact over some period of time. THAT is not at all like the random, in passing, casual contact when out shopping.
A large after-action contact tracing study looked at where a many thousand group of New Yorkers had obtained their Covid-19 infections. The largest percentage was at home. The second largest group was in healthcare/nursing care related facilities. Together that was more than 80% of the cases. The minority, 20% was scattered around many different venues.
So, based on data, where - in those cases in that study - would masks have been the most helpful? In the home, not while out doing daily chores in public, where contact is usually not close, not in close spaces, and not sustained over some period time.
Fine, lets just wear Hazmat suits all the time.
If masks are so effective then why have cases gone up everywhere there has been a mask mandate?
Once again go back to the data from the Diamond Princess cruise ship last Feb.. People sharing the same cabin, one got it, one did not. 50% of the population have a cross immunity to the virus. It is also spread by Fecal-Oral, especially in Hospitals and Nursing Homes.
Viruses. Of which there are thousands. Exist everywhere and circulate in the atmosphere
They’re everywhere.
Covid is simply a GIANT COMMUNIST TAKEOVER PLOT WORLDWIDE

Flaw in your logic. If ‘random, in passing, casual contacts when out shopping’ do not result in infections, how would those involved in those ‘casual contacts’ become infected to bring the virus home?
