I was almost evicted since my landlord wanted to make more money with Airbnb. Before that I've already heard of cases how in tourists towns the local poorer population wasn't able to get long term apartments because richer tourists filled them through Airbnb.
Airbnb is cancer for the local population in any country that isn't very rich because locals & students then have to commute from further distances.
So banning Airbnb would be godsend for the local population of many countries, if you want to make money with renting open a hotel.
Obviously there is the argument "I own the apartment so I can do whatever I want". I really have no good counter argument for this as it is true. But all laws are really relative to the culture. This same person could then say "I don't owe the country any taxes because _I_ made the money".
So this just goes to show that we "normalize" everything based on laws.
For the greater good of the local population in poorer countries Airbnb should be banned.
