This is not limited to cities and Airbnb, but it's a general trend that pushes cities and countries to figure out sustainability of tourism. There are other examples like islands where the tourist attractions were destroyed because of lack of regulations - Maya Bay in Thailand or Boracay island in Philippines were closed for extended periods of time. Now they need to figure out how to prevent the situations that led to those closures from happening again, and imposing some limits on number of tourists is one of the possibilities.
