Beach Access is not a right... it's a privilege... and you probably have to pay for that privilege.
Absolutely insane. Shoreline belongs to everybody with free access to it. Look at more advanced countries: they have laws for that. Your shore has been eaten little by little by private interests, and you let them do it.
The one good thing about Hawaii is there are no private beaches except for those controlled by the military. There are some laws about use but the Department of Land And Natural Resources are spread so thin enforcement is unlikely.
