Keep in mind that most everything you do with the intent of harming landlords ends up also harming renters in some ratio.
I lived in houses rented by these part-timers and they were pretty haphazardly managed compared to the [fewer] times I lived in clearly corporate-owned and managed properties.
Even if you think the perpetuation of capital unfair the realities need to be acknowledged in order to even begin to think of a viable alternative.
