I think you're overestimating the magnitude of lost revenue. We're talking about 1 month of lost revenue.

A profitable restaurant's unit model might be: 10% net profit, 30% COGS, 30% fixed cost, 30% labor cost

During this one month shutdown, the restaurants won't incur labor cost or COGS. So, they're really only in the hole 30% of one month's revenue. With a little back of the envelope math, you'll see that the restaurant owner can pay back a loan for this amount by allocating 10% of their monthly profits (or 1% of monthly revenue) to loan payback.

Now, if the restaurant is NOT profitable, then we have a problem. But, they were probably going to go out of business soon anyways in that case.

You're forgetting that businesses can jack up prices after a crisis. Let's say there are 10 restaurants. One of them survives because it has taken a loan and others just crumble. Suddenly all the competition is gone and people are storming your place.
