Yes , there will be enough space between non vaccinated people that the virus cant jump hostsThere is also a chance that in a short period of time... (absent new variants) Covid will be so low that no one is going to care anymore.
I am not saying that will happen I am simply stating that with half the population vaccinated and presumably much of the other half low risk... the only people who will be dying are the really dumb high risk or the high risk who can't take the vaccine for some medical reason... and perhaps maybe Christian Scientists.
This is why its a bad idea to put the non-vaccinated people together in one group
