The Hawaiian Homelands are owned by the state, not the indigenous. And the office managing these affairs is a public office. The ethnic Filipinos, Chinese, whites, etc own that land as much as anyone else, and own that office as much as anyone else.

The public owners grace the Hawaiians with a racist policy allowing their exclusive use at the expense of denying persons within the jurisdiction of the state equal protections under the law. But only at the graces of the other races allowing it, and at the grace of all races voting for the office managing these affairs. I think you are thinking of something like a reservation where the Hawaiians would own that land.

I'm of the opinion there is quite the chance, just like their racist voting policies were struck down, that someday someone of the wrong 'blood' applies to use that state land and they will challenge their denial under 14th amendment. So far I don't think anyone has bothered, but it is certainly on my bucket list for when I'm retired and have the time for a pro se case.
