It isn’t true that Jews can live wherever they want in the US. Technically and legally they may be able to live where ever they want. Safety wise they certainly can not. There is a reason why Yeshiva D’Harlem closed down and why Chaim Berlin did not move to East Flatbush after starting work on their building and why Brownsville which was once called the Jerusalem of America is now Judenrein. Etc.
And at least in those neighborhoods the people who choose to live there are only putting themselves at risk. Living in Gaza is putting unwilling others at risk too.
As long as we are in golus there will be places that Jews can not live in. Including in Eretz Yisroel. You may as well complain about the parts of Lebanon that are halachically Eretz Yisroel where Jews can’t live either.
