Modern landlords to not “provide housing”. They extract rent from the use of a house that would otherwise be available to purchase by the renter if not for the landlord holding it for rent extraction. Worse still, since rent seekers compete with homeowners for housing they end up driving up the price, which prices out homeowners and creates the demand for renting to begin with.
Any other “service” a landlord provides would otherwise be levied as those services are provided (like a handyman or contractor being paid for work done to your house). In the case of the landlord, the rent extracted is maximally realized by providing the least amount of service (even none) for the most amount of rent. Rent is completely detached from any actual labor or addition of value.
