It isn't about the Dow. It is about the restaurants that don't have cash-on-hand having to close. It is about the people who live paycheck-to-paycheck now having to decide how to spend their last twenty dollars with the only hope of relief being a measure that is still being debated. It is the factories that are shuttered.
You could make this argument about any potentially fatal disease. Are you willing to crash the economy to save the people who die of the flu every year? Probably not, right? Presumably because fewer people die of the flu.
It's an unpleasant reality, but it's a question of degree--how many lives are worth saving the world economy for everyone else? If your answer is "zero", then why should we not apply that standard to every other disease?
The last thing this is about is the Dow.
