First of all, this is a brand new virus. There is doubt that people can develop long last immunity to make herd immunity work. You cant just experiment, people's lives depending on it.
As to the death rate, its very unreliable. However, regardless of what the death rate is, just look at the real time footage from the epicentres. Italy, England, New York, Wuhan. The local health care systems are absolutely SWAMPED. And that is only a small fraction of population being infected before full shut down starts. So one would only wonder, if you let it 'rip' through the population, and see what the world would be like.
A brand new virus also meant we dont know if the infection can cause long term consquences. For example, glandular fever - the EBV can cause chronic fatigue, Chicken pox virus can cause shingles and post herpetic pains. Ross river virus and its cousin Barmah forest virus can cause arthritis. And there are host of conditions that human suffer like rheumatoid arthritis, Ig A nephropathy that scientists believe they may have an viral aetiology.
Until we have all these information, I do not think we can risk it.
