That's what's so sad about your argument. Your idea of "success" is that 50% of LA came down with it, despite the strictist in the nation standard employed by Los Angeles, at a tremendous cost to children, small businesses, homelessness, crime and poverty. If this is success, wow!
The conclusion would be that given the tremendous cost, maybe Los Angeles shouldn't have done much of anything....how much worse could it get....Stockholm? New York City? The other conclusion from it would be maybe these NPIs are fruitless in large mega cities, which were doomed anyways, but maybe could have made a difference in places like the Dakotas...given Finland, Estonia, and Norway I doubt it, but maybe.
