We should only give authoritarian power to a government when we face a near extinction level threat. The government won’t return that power when the virus gets cured. Look at every authoritarian government in power today and through history. Almost no authoritarian returns that power.
Coronavirus actually has a far lower rate of death than we thought. It kills old people and those with preexisting conditions primarily. The massive shutdowns are going to kill more people over time through the loss of our freedom, suicide, economic collapse, starvation, and other diseases.
Even if no one died and no money was lost, the loss of freedom is not worth it. The government will abuse this and wreck our lives long run.
