Well I am a landlord, as I think I've mentioned before.
I was a landlord, and like you I tried to carefully choose tenants. Still, that's not a guarantee when stuff like this becomes law (which is one of the reasons I stopped being a California landlord).
I understand hard times and would have no problem working with a tenant, but this lowest common denominator stuff that gives tenants carte blanche is ridiculous.
Even if a landlord doesn't have a mortgage, for many of them, especially older, retired people, the rent might be a majority of their income. It's unfair to simply give everything to the tenant and nothing to the landlord. Especially if the tenant might be some millennial telecommuter who is actually still being paid. I didn't see (there might be) anything in this plan to check tenant incomes affected by covid.
To me, this is just another step towards "property is evil". And eventually, as I have harped on in the past, the only result of stuff like this is small, independent landlords that tenants could have a relationship with, saying, "screw this". Those tenants can then deal with housing shortages and corporate landlords with lots of lawyers on staff.
