Even the way you present it is as if users of AirBnB are ripping everyone off ("consequences of his actions...").

No, my observation applies strictly to those who rent their apartments in violation of their leases and/or local ordinances.

..even if the thing is bad, which is debatable in this case.

You're welcome to debate whether "the thing" (subleasing his apartment in violation of his lease -- for a huge profit) is bad or not, but to me it seems pretty clear.

But here you imply that anyone breaking a contact of adhesion is a bad person. I literally cannot rent a suite that doesn't forbid sub-letting, even though local law forbids forbidding of (reasonable) subletting.

And if we then say, well it's not bad in my city because the contract that tried to prevent it wasn't enforceable, we have to step back and ask how it's magically bad in another city with different laws.

I'd rather talk about actual harm, or rather lack thereof outside scare stories, to buildings and other tenants. No harm, no foul, and harm to abusive contracts doesn't count.
