Excuse me, but if a libertarian website tries to paint the landlords as victims by giving some extreme (but still anecdotal) examples, I'll take that with a grain of salt. Especially the first example:

>Gao discovered that one of his former tenants had given her keys to a friend who had moved in without permission. Gao has never met the squatter now living in his house and is afraid to contact this person out of fear that he'll be sued for harassment.

So it's not that the tenants were forced to stop paying rent, someone who doesn't even have a rental agreement has simply moved in, so the landlord would have every right to get them evicted, but chooses not to for... reasons?!
