When someone decides to turn their apartment until a hotel room, it affects all of their neighbours. They can't then decide not to participate in the sharing economy, it is thrust upon them unwillingly.
At any rate the armchair philosophers should not advice others on what should be allowed or not.
Apartment complexes don't have HOAs and sometimes it can be a huge hassle to contact your landlord to fix the sink, much less to investigate and shut down your neighbor's illegal Airbnb operation.
