The study is important because of the social structure of control here. It’s one thing to observe no effects from national lockdowns. There are countless variables here that could be invoked as cautionary notes: demographics, population density, preexisting immunities, degree of compliance, and so on. But with this Marine study, you have a near homogeneous group based on age, health, and densities of living. And even here, you see confirmed what so many other studies have shown: lockdowns are pointlessly destructive. They do not manage the disease. They crush human liberty and produce astonishing costs, such as 5.53 million years of lost life from the closing of schools alone.
