I'll present an argument against quarantine being warranted: Covid-19 is an endemic virus for which there are no sterilizing vaccines and hence "zero Covid" policy frameworks are an insane and hopeless attempt to turn back the tides. You will either live under these restrictions for the rest of your lives, or give them up and eventually be exposed to the virus.
Consider, however, that being exposed to the virus after being vaccinated reduces your risk of death and/or hospitalization by a factor of 10-20x. The assumption that there are “no sterilizing vaccines” is a little questionable too - even against Delta, the FDA approved vaccines are showing 40-50% immunity against infection, i.e. sterilizing immunity.
Zero Covid countries like NZ and Australia that re-open to the world once their populations hit 80% vaccination will have prevented many deaths among their population.
