I do think there is an injustice in draconian coronavirus measures because this is a low risk event ultimately. So by making everyone change their entire lives, we are making it so everyone gives something up so that those with a higher (but still low) risk can continue to go outside and partake in business, leisure, etcetera to a limited extent. This was the alternative to instead having just the risk averse or vulnerable quarantine themselves if they feel the odds are not agreeable (they could just self isolate and face nearly no risk). Put another way, lockdown measures and other mandates or restrictions trade the freedoms, leisures, financials, mental health, and stability of the young, healthy, and personally responsible to reduce the risk exposure of other people to an amount where the other people can live a slightly more normal life than otherwise.
When I see children losing a year of socialization and education so that a small proportion of the very elderly can live slightly longer, I feel like we are making a disastrous tradeoff.
