I assume you were being sarcastic, but you have misunderstood the point I was making.
It’s a popular idea that if only we had all done this or that in the beginning, everything would have been fine. But most of these hypothetical “if onlys” such as “hard lockdowns” were completely impractical at the time. Not only would it not have worked, a hard lockdown could not have been implemented. It would have been physically impossible. And the point of all that musing was “how is it that this did not occur to a very intelligent person”?
Taiwan has rather dug a hole for itself, as I mentioned several weeks ago. Eventually it was bound to succumb. It’s just a pity that that happened before an adequate vaccine supply had been secured.
