Your comment seems highly tone-deaf. Look at some of the comments above about pollution and what it has done to areas immediately outside of the city core.
The air quality in Paris has significantly improved over the past few years, thanks to multiple initiatives to reduce the car traffic, both at the city and regional level [1].
Some of the places where it got worse are far away from Paris… so who cares about the poor people who live in a far-away suburb near the freeway. It's not like they vote for Paris' mayor.
I live in a high-tourism city that is not Paris and AirBNB severely reducing the amount of housing on the market is definitely a problem that high-tourism cities are having.
