Religion

Something that is meaningful to one is not necessarily meaningful to another. For all the sacred value the site might have for Hawaiians, this is balanced by the 'sacred' value the astronomical data that site can obtain that cannot be obtained elsewhere on the earth.

That said, we as a society and particularly as a government, have abused the everloving fuck out of indigenous populations everywhere.

Therefore, while 'sacred' is uninteresting to me, I do think 'we' should go out of our way to ensure the project 'worth it' via some sort of concession and is overwhelmingly supported by the indigenous population. Particularly because of the watershed and cultural significance. If that means an open checkbook and 'what will it take', fine. That data is worth billions in concessions to the locals for environmental mitigation, and cultural concerns.
