Anyone advocating that as the goal for society needs to present a plan that has a high chance of succeeding without an unreasonable burden being placed on society. I think maybe the development and mass-deployment of rapid tests for the virus could achieve that, but ironically we don't see much emphasis on this strategy by lockdown advocates. It's almost as if the opposition to the lockdown is all the proof needed to convince some of its advocates that it's the right strategy.
On a side note, we now we see that the lockdown advocates have simply switched their rationale for the lockdown, from "flatten the curve", to "eliminate the virus from the population", once the curve was flattened. For those who believe society is better off being tightly controlled, with heavy restrictions on individuals to achieve larger goals that benefit the public, the coronavirus is the gift that keeps on giving.
