Providing space for rent, especially to restaurants, is a gamble already in normal times. So one could argue that missing payments is part of the natural risk property owners have to bear.
On the other hand one could argue, that a government has to pay damages for business lost if they implement regulation shutting down that business.
At least, that is something that is part of modern international trade agreements. I know I shortened the argument here.
What I am trying to get to is the fact that there are no easy answers and that potential solutions will necessarily be colored by political leaning. This is a situation that is new and not solved with an easy fix.
