Much epidemiological research before COVID seems to have had a general consensus that quarantines are most effective as a temporary stopgap measure and when targetted at the most vulnerable population. Unfortunately with COVID, lockdowns became more of a political policy than a health measure, and people were either for or against (like with any other political issue). And the WHO (which clearly has been trying to cover its ass throughout) never really made it clear if their priority was to reduce the infection rates or reduce the mortality rate. You don't need to go to med school to know that treatment and prevention are too different things.
In a country like Argentina where it seems like everything is political already and with its history of political violence, things could have actually played out much, much worse. Nowadays, far-right elites in Latin America (with a few exceptions) just fly to their second homes in Miami whenever things get too hot for them, rather than plot military coups.
