That's a nice just so story for the cases in which a landlord benefits due to the success of his tenant. Now do the ones where the property value goes down because of any of a zillion other factors.

Spitballing solution: In addition to LVT, rental tax? Nah, that just drives the purchase price to a higher level. Hmm. Also it drives up the cost of the minimal viable business (hence the coffee sheds in parking lots).

Allowing more supply is the only good answer.
