I understand your point, but we need a healthy, functioning global economy to have the resources to tackle global-scale problems. Going crazy, whatever that means, is going to fail because it won't be possible to sustain efforts as the economy shrinks. What we actually want to do is to pay a relatively tiny cost now to avoid a much larger cost later.
