Kind of hard to have any local culture when everyone local is pushed out by rich elites from another country who fly to commute and can afford to have two homes in two countries. AirBNB, "nomads", and the likes are city killers.
Does not mean you're rich per se. Not poor, sure. Also yes, you said fly in, but there's really no difference if they fly in or go to their weekend house on Thursday or Friday by car, they're not here. I think the main point is the "is the person actually living there or visiting twice per year", because I think that is killing neighborhoods (if people talk to each other, not the case here in my building).
Stay in your country, thanks.
Talking down like that to locals really fans the flames of the latter solution. Probably not good to do it.
If you live in a nice city (and Barcelona is a great city, truly a world's treasure), it attracts tourists, by definition. I don't think anything can be done about that (except maybe ban AirBnB and introduce hotel tax -- but they will just live in places nearby and drive in by cars). You can also of course make your city less nice (by riots, crime, graffiti, trash, whatever), but this is shooting oneself in a foot.
The "problem" has no solution. Great cities are attractive, people want to go there, and have the legal right to.
Locals can do things to regulate tourism by economic means, but you can't say "don't come", except on state level. The city is not your property.
Other cities would require a wall.
No they wouldn't. Just higher fees on hotel rooms or congestions charges for cars. It's possible to reduce the numbers visiting any city.
The same logic should also work for states; people, however, are irrational in this regard.
If a city feels its culture or inhabitants quality of life is being adversely affected by tourism then it is fine to control the numbers.
If you look at places like Venice part of the criticism was the hordes of people arriving that don't spend any money. They bring packed lunches and just clog the place up. There are plenty of products and services that manage demand by increasing prices, I can't see why these places should be any different.
Luckily it is feasible.
at the Twopenny Hangover, the lodgers sit in a row on a bench; there is a rope in front of them, and they lean on this as though leaning over a fence. A man, humorously called the valet, cuts the rope at five in the morning.
