I think the comment above yours is referring to 'natural' rights which are generally negative (i.e., no one can take them away from you). If anything can become a right simply via declaration or popular vote, can 60% of a country's population vote themselves the right to the property of the 40%? By that logic, the Nazis had a right to exterminate the Jews because the Nazis were democratically elected.

I understand wanting to protect Hawaii's heritage, etc. but landowners should be free to sell the property to whosoever they deem fit, at whatever price.
