Interesting read, but it ultimately comes down to the cooperation of the population. In China it worked very well as the people don't have a choice but to 'cooperate'. Lock downs are not only effective in controlling the pandemic, they also prevent more viral mutations by keeping the active cases low. More active cases, more chances of a successful mutation creating more virulent strains.
This focus at only looking at deaths and hospitalizations conveniently ignores the risk of creating worse strains. Meanwhile pointing fingers at careless lab workers that might have started the pandemic. The entire world is a breeding ground / test lab atm. 11,727,029 infected humans walking around atm in which the virus duplicates constantly.
And there's always desensitization at work. At first 3,000 deaths were bad, now we're used to seeing double to triple that number daily as a baseline in between waves. Lock downs get less effective over time as less and less people think it necessary.
Covid is here to stay like the flu. Yearly Covid booster shot will become a thing. At least less deadly strains should win out over those that kill their host or make them too ill to spread the disease on. Yet long covid could very well become a big drain on society.
