>In case it is forbidden either by rent contracts or by law, AirBnB/Uber are, in this case knowingly, assisting parties in illegal acts and should be punished as such.
Forbidden by Contract is a civil matter and AirBnB has no way of knowing this or should care at all
I am 100% opposed to laws forbidding property owners from renting out rooms either short or long term
In either case this is 3rd party liability which should not even be a concept in American Law.
>When I'm e.g. a store operator and knowingly buy and later resell stolen goods, I'm punishable as part of a criminal organization
If you can not see the difference in a person selling OTHER PEOPLES stolen property and a person selling THEIR OWN property then I really do not believe we are going to agree on much here.
>The only difference between said store owner and AirBnB/Uber
No the biggest difference is One company has the complete permission of the property owner to resell/rent the property, and the other does not.
