Hi Christyl, thanks for your comment and thanks for reading :)
Based on your description, it sounds like you served more as a maintenance worker and property manager as opposed to purely a landlord. My critique pertains more to landlords who outsource that work (which is a lot of them), and the landlord-tenant system as a whole, which, as you said, is not only harmful to tenants and homeless people but also sometimes to people who somehow become ensnared in the system on the other end.
As I said at the end of the article, it's an institutional problem, not an individual one. Some landlords are good people. It's kind of like with cops I suppose. We can be extremely critical of police systemically but also acknowledge that some cops are compassionate people, even if they're rare. But the problem with both cops, landlords, CEOs, etc. is that within our system, they're institutionally incentivized to screw over people who have less power than them. So there can be nice landlords, but that doesn't mean that landlords should exist in the first place. Like you said, private property ownership is not the only way housing can be organized. It's incredibly inhumane
