There is no problem if this is just one person or one business. There's no issue with allowing people some time to find the next renter.

The problem is that when everybody leverages to the hilt and the whole area collapses, the rent prices stay high even when there's no one renting--which is bad for renters. And this continues in a gigantic game of chicken until some of the owners finally run out of cash and go bankrupt and everything collapses simultaneously which also isn't good for the end renter.

It's like the 2008 Wall Street crash. Lots of people knew what was going on. However, everybody knew that they were equally screwed whether they were responsible or not. So, they just rode the train and hoped they could cash out to the next sucker before the disaster.

And then we get the joy of everybody wailing that they need a bailout.
