If we have to make the choice I think it is reasonable to privilege the concerns of people who live in a place year-round over those visiting for a week.
Let's say a 400 square mile area of land can only accommodate 10 million people, but that 2 billion would prefer to live there if they could, because it is one of the nicest localities in the world.
Why have 10 million lucky individuals get year round access to it, rather than giving 1 billion people 3-4 days each to visit it?
Maybe the most desirable locations on Earth should be theme parks that a billion people can visit, rather than gated mega-communities for ten million wealthy/lucky long-term residents.
Maybe one day the typical life will consist of visiting a different theme-park-like city every few days, and people will identify with their planet rather than a few hundred square miles that's designated as their city of residence.
