You're treating the population as a homogenous mass, indistinguishable from each other. That assumption is not correct. Look at age, existing health conditions, smoking, drinking cohorts and you'll see that certain groups have much higher death rates. Also consider that some infected people do not show any symptoms. The diagnostic kits are limited and take time to process. When a cluster of people get symptoms, they overwhelm health services. All of these issues and others combined can cause chaos in an undefined way. The most harmful effect is loss in faith in society and the economy as we collectively regress to a scarcity mindset.
