I wonder if this community group has contemplated what will happen to Lanai and it's people if they succeed in driving the hotel and golf course out of business? Since Ellison owns 98% of the island, I would say it's mostly his water anyway. Push too hard and they'll find themselves in the same position they were in when Murdoch got tired of Hawaiian activists trying to extort him and shut everything down. 
If the only business on the island cannot be sustained, neither can the population. Even the uneducated folks should be able to grasp that concept.
