It’s crazy! Like, even if for some reason we want to keep the whole landlord thing going, there are guardrails you could put up to prevent them from rotting out the cores of our cities.

Like, make it so the current tenant gets the right to keep paying the current rate until the landlord finds someone who’s willing to pay the higher one. If someone wants it, great, fine, you can close the old business and let the new tenant open. But if you can’t find a new tenant for the higher rent, don’t let the building literally rot instead.
