Yes, of course, a landlord does managerial work that should be compensated.
Cool we agree there at least.
But ownership of the building is not necessary for the ability to do that managerial work, nor is doing that work required for the legal entitlement of the collection of rent.
I dont recall anyone saying it was necessary that the owner of the resource be the same person who is deriving utility from said resource.
These can of course be complete separate resources. In which case the person who owns the land is providing the utility of selecting/screening the most effective managerial service. The managerial service is then outsourced to do the actual management. In this case the utility is provided in multiple steps is all. But the landlord and t
he rental service are still providing a utility.
The landlord isn’t even usually the person who built the building or repairs the fences.
Not always, and as I just covered when they are separate then the landlord is providing a different utility than the managerial service. But both are still providing utility.
