Epidemiologists see the public health side, economists see the monetary side, doctors see the reality of the disease and judges see the constitutionality. For what it's worth, most economists and doctors I know are against shutdowns. Guys like Fauci have to say what they say without regard for the economy (they give advice, they don't dictate policy, ultimately policy is determined by governors and local health departments), otherwise they will be accused of not acting in the public health interest. Judges have to determine how much authority the constitution gives to certain entities (ultimately we all have personal accountability for our actions and should not blame the government when we get sick).
The reason I would be against a shutdown in January, is it obliterated the economy in the spring when states enacted their own shutdowns and it would set the precedence for another shutdown in March, another in May, ... (how many times have we heard one more week, two more weeks, ... during the pandemic?). Basically if the fear mongers get their way, we will be under lockdown orders until the spring. People are going to die (if we destroy the value of our currency, far more people will ultimately die). Those who are most at risk should voluntarily isolate themselves if they have concerns. The transmission vectors for this disease are well understood. People can choose to behave how they feel is in their self interest. If an employer wants to mandate masks in their establishment, they are free to do so and consumers are free to go elsewhere. If a bunch of rednecks want to get together maskless and kill each others friends and family members, they are free to do so (isn't that what Sturgis Rally was all about this year?).
