There's certainly some broken window logic being applied, but not 100%. There's no doubt that some economic decisions (investments, employment choices,etc.) made before the virus would not have been made given what we know now. If we had an impossibly flexible economy where everyone could be immediately rehired as deliverers and expert physicians and restaurants and assets could be reatomized into hospitals and toilet paper then maybe the impact could be very small. It's possible that in such a world the investment decisions made not knowing the virus was coming wouldn't differ much from the decisions that would have been made with perfect prescience. But in reality there will be some cost caused by the difference in economic choices made not knowing this was coming. The sum over everyone's future income streams will be smaller than they would have been because of worse resource allocation. I agree it won't be the full $3T but don't have the expertise to estimate it.
