If you think people are worried when stock prices are falling, imagine what happens when they all go to zero. That's what happens when you close the markets: stocks can't be sold and thus have an effective value of zero.
Much of the fall so far is bringing prices back to reasonable levels after a record-setting bull market. Not that that's especially fun news; between that and a genuine recession coming up, a lot of people will lose a lot of money. But it means that, as scary as this is, it may also be necessary, and even beneficial. (In the "long run", that is, and in the "big picture". Still sucks for a whooooole lot of people for a very long time.)
