If they lose this “right”, they insist on becoming pure profit maximizing machines?
It's disingenuous to pretend like the landlord is the only party with any control. Landlords cannot remove a tenant at "the drop of a hat" by any stretch of the imagination, nor can they arbitrarily increase rental prices. Rentals usually involve a lease that protects the tenant from arbitrary removal and price modifications as much as it protects the landlord from unexpected vacancy. If you're renting, you should know when your lease is up and know that the landlord has the option not to renew and/or to modify the price. (If you're in California, you should also know that the new law punishes your landlord for trying to do you a solid and keep your rent stable across lease terms.)
On top of conventional lease protections, virtually every state has default tenant protections written into statute that can't be overridden by lease agreements, and that include a default implicit month-to-month tenancy term, providing at least basic protection from out-of-the-blue demands to vacate.
If an eviction must occur, it has to be conducted as prescribed in state law. Tenants overstaying or defaulting on their leases frequently can't be removed without 3-6 months of legal wrangling, which is no fun.
The CA law allows the rental price to reset to market rate for a new tenant, so unless the landlord doing you a solid was planning to stick you specifically with a rent increase down the line to recapture the present solid, they can still keep your rent stable across lease terms.
Maybe inflation gets crazy, maybe taxes increase, maybe maintenance turns out to be more expensive, maybe they realize they've been underpricing, maybe they sell the property to someone who has the same reasons.
If you tell them that you will limit their freedom to choose the rent price, they will try to retain as much freedom as they can.
It's like a use-it-or-you-lose-it budget game.
Needless to say, costs are increasing faster than 60% of inflation... In turn, landlords are only willing to write leases at very high prices and the supply of rental units is even lower than it would be otherwise...
