Purely anecdotal, but my earliest experiences with AirBnB were all staying as a guest in someone's home, which typically doesn't violate local regulations. You're allowed to have occasional guests crashing in your guest room in most residential areas. Now, of course, AirBnB encourages fully investing in it as a landlord platform, where you rent and automate multiple whole properties and never meet the guests. That behavior lowers the quality of life in many tourist destinations today.
