they have 99 % of the planet to live in, this is literaly the definition of entitlement when a group is pushed out of spaces and creates their own, then the same people that expelled them become ofended because THEY CAN'T HAVE THIS ONE THING CATTERED TO THEM.
Krakoa isnt for humans or those heroes because they dont NEED IT, they can live ANYWHERE WITOUT THE DANGERS MUTANTS SUFFER, they have new jersey, new york, the entire united states, the american continent.
Mutants ONLY have krakoa, they NEED to protect one another because no one else obviously will.
Im pretty sure even in the real world rich people have more private propriety and islands a normal person can't get into than the entire mass of krakoa wich is very small island, an tiny island without even a million citizens.
Humans DON'T NEED KRAKOA and their "immigration" can easly become colonization or gentrification, as it happens in the real world, like Hawai, or even genocide since humans have already caused a terrorist atack.
Once again I share this because you are missing the point.
