Even if the fatality rate for non-old people is only 0.2% that's still impressive 80k dead Possibly, the isolation is not going to be purely age based, but young people that are more susceptible to the disease might be isolated, in that case the fatality rate could drop significantly. The problem is that in many cases it's hard to know whether you're susceptible until it's too late. It can be an undiagnosed pre-existing condition, or caused by stress (e.g. due to the crisis itself). For many working adults it might not be easy choice to self isolate (must provide for family etc) so many might likely downplay their susceptibility. And this is all just talking about fatality rate while hospitals still function normally.
