You are an idiot for only considering the number of deaths. The economic disruption is caused from the fact it is highly contagious not the number of deaths. The markets do not care much about 1 million sick and old people dying. But regular people do care about spreading the infection or catching the infection, when those deaths could be themselves or loved ones.
People have been getting hospital treatment so far, put on ventilators. If the hospitals get full the death rate will climb much higher
Drunk driver killing you cannot be avoided. Cardiovascular cant be avoided (in the short term). Obviously you are going to change behaviour for something that can avoided and controlled in the short term.
Doesnt matter if your IQ is 80 or 150. You are not going to want to bring this virus home to your wife, children and parents. Or take them anywhere once 10,000 people a day are dying from this.
