The historical solution to this (illegal tenant in an illegal short-term sublet doesn't want to move out) would be to have some vowel-suffixed friends encourage them to move out. Which isn't exactly "nice", but at least has the virtue of being nicely economically efficient.
Landlord ends up in jail, and property ends up destroyed. Since the landlord probably doesn't have insurance, or has voided that insurance several different ways, it's an expensive method to achieve nothing. And that's if the tenents decide to leave, because they could just stay.
I was thinking something similar, the AirBnb host however doesn't think of themselves as doing anything illegal so they constrain their thinking in that way. I have certainly met people over the years who exploit this in others.
that's true, I guess a lot of underground markets, black markets operate under the hand of physical enforcement or intimidation, I guess the more unregulated a market is, even lead to death. ex. drugs, prostitution etc.
