I found this article below very interesting:
It seems to me that for those retailers that survive their "apocalypse" some relief may be on hand in the form of lower rents.
As well as the link above, I recently listened to the Pets at Home call, where they were talking about achieving 30% rent reductions, and others are achieving similar numbers.
What I hadn't appreciated is the additional benefit that when rents come down so, at some point, do business rates.
If you own a business where the shops remain profitable today, it seems to me there may tailwinds for years to come...
