"I think this is a valid point, but one consideration that feels missing from a lot of these kind of disucussions is to what extent the economy will "come back", even if every restriction were lifted."
Because there's no point debating such a question. Arguing that we should leave lockdowns in place because people would be too scared to go outside even if we lifted the lockdowns, is tautological.
If the argument is that people are going to stay home anyway, then we should open the economy on first principles.
