"It's likely that the marginal harm to the economy of a full shutdown (given that you're already mostly shutdown) is less than the marginal gain in fighting the disease."

That is what I push back on. I dont think I agree with this. "Marginal" to me implies "as we go forward". Each new day. As I wrote, the marginal cost/benefit going forward should increasingly shift from attention on epi curve to eco curve. This natural and expected. Any failure by government in this regard is on them.

The primary reason for implementing mitigation measures to flatten the epi curve was to prevent a substantial over-taxing of hospital resources, especially ICU resources. As it continues to show that this has and is generally working, then attention should naturally shift to mitigating economic harm caused by the mitigation measures. As long as our re-employment of the economy doesn't threaten that threshold peak of the epidemiological curve, we should smartly do so.
