Yelp data shows 60% of business closures due to the coronavirus pandemic are now permanent

You can close you business or you can "CLOSE" your business. If you just close it, you continue to accrue expenses - rent, taxes, etc. CLOSING your business stops the cash drain. I'd expect many to reopen when the conditions are favorable

I am not an economics guy, but I would imagine that many of these businesses closed because they just don't have the cash reserves to keep them open when there is no real date on when things will open. The local governments seem to be closing things on a whim (closing malls on Thanksgiving for example). My guess is that these businesses will come back after there is a vaccine.
