So not only do you admit it would never happen, you cannot even provide any actual figures to support your claim. New Zealand and Taiwan have had success because they effectively eliminated the disease at the start of the pandemic, they didn't shut down with 30% of their population infected and millions of current infections, which is why that particular comparison is poor.

It isn't unreasonable to ask for justification of your claim that it'd be so much cheaper to shut down the global economy or take 'severe' action at this time. So, thanks for providing absolutely nothing beyond some vague claims about ideal actions that won't happen?
