The details of managing the economics are more than a footnote, but if the worst possible peak isn't avoided everything else becomes irrelevant, because there's no surviving economy to speak of - except maybe one of local barter.
The economics are not externalities. The virus is.
The economics are a social and political choice. They don't actually require money or other symbols, although they'll probably be mediated through for reasons of comfort and familiarity.
They require enough basic provision of food and services to keep people alive, and enough provision of shelter to keep people from rioting, especially once winter comes.
The worst possible economic outcome - after a Killer Peak - is a critical mass of angry and hopeless people with nothing to lose.
Realistically, avoiding that will probably mean helicopter money and aggressive price controls to prevent gouging and profiteering. The usual rules about inflation won't apply because the alternative will be a cratering depression and mass deflation which will do far more harm to the economy than hand-outs will.
It may also mean something worse, like some form of civil conscription to get essential work done. I really hope that doesn't happen, not just because it's better to call for volunteers first, but because it's so easy to abuse politically.
But it's also true this has the potential to become the equivalent of a war time situation, and in extremis the rules may need to change to keep food+lights happening.
Shit choices. But it's a shit situation, and IMO there's no chance of business as usual returning for quite some time.
