What do you consider “very rapid”? It has spread significantly faster than the swine flu epidemic did in its first two months.
> I have predicted, and continue to predict, that when we're looking back at this, the response to COVID-19 will have done far more damage than the virus.
That is rather likely and would mean that the containment efforts worked. Remember that the economic cost of containment shouldn’t be compared against the damage caused by the virus, but by the counterfactual damage that would be caused by an uncontained pandemic (which would be absolutely catastrophic given that the case fatality rate rises to the mid single digit percentages once healthcare infrastructure is saturated).
