Yes, I know the cost of housing is insane and something should be done about it, but introducing some level of market efficiency isn't necessarily a bad thing.
I can't speak for the US but in the UK a huge majority of private landlords are individuals, many of who want to earn a living from renting out two or three homes max. I rent an office from such a person, his sense of entitlement is off the scales.
Some of these landlords had the homes fall into their laps via inheritance, some are simply playing an arbitrage game, very few are actually doing anything economically productive.
Anything that threatens this method of exploitation has to be positive.
