African-Americans (descendants of enslaved African peoples) have the United States as a "homeland."
There are areas that have been known for their being Black, though ignorance on the part of the people living there, and racism on the part of the White surrounding populations have not given into full ownership for Black people.
There are majority Black islands near the US as well as countries like Liberia and Kenya/Ghana that have easy citizenship processes and certainly do want more investment within them.
You can either choose to double-down in the US or let your capital fly to another place, but conceiving of some kind of Zionist project for AAs (again, Liberia is a colonail reference for this), is foolish.
