you indeed will not compromise on your principles
I think many property owners might be willing to return to Ancient Customary Use, defined as: the right to transverse the coastline, swim, fish, take family photos, on the entire 26 miles of 30A coastline and the right to use beach equipment on County Property (during approved hours) or State Property (with a permit) or Private Property (if no objection by the Private Property Owner).
I don't think many (if any) property owners (beach front or non beach front) would be willing to renounce their property rights (in particular the right of exclusion) and give those rights to the BCC. There may be a concern by some of the free for all and chaos that could occur under the exclusive BCC control of property rights. What about non-beach front private properties owners down the street from a restaurant? What if the BCC allowed people to park on their property at no cost (but the property owner would need to fix ruts and pick up trash), or even allow the restaurant to set up extra tables and chairs on their private property, because the restaurant was too crowded for the property they owned, and the county needs the "tourists money" and the restaurant owner wants to expand? Is the BCC allowed to TAKE property rights against the will of ANY property owner? What if the county just paved over that property owners front yard to make parking for the restaurant or a beach access? Would that "reasonable"? This is not the same as "Eminent Domain" but "Taking". The BCC has filed a lawsuit to "take property rights" from beach front property owners. If successful they will expand it to other property owners. Why would they stop? What about taking property to build a new ball park? Of course they would also need to take more property for parking and concession stands. It is for the good of the many and a poll shows most people want free land for a ball park.
If someone is not willing to renounce their private property rights and give them to the BCC for exclusive management, some of properties which have been in the family for generations, then that is a sign of "not willing to compromise on principles"?
I also think you are right that the "CU fight" (formally known as beach nourishment plan to remove property rights) will be reinvented as a constitutional push to remove property rights from a selected targeted population of owners (aka beach front property owners) or maybe as a push "Incorporate 30A" (so they can create new laws to take over beach front property)? Either way this looks like it is going to be long and expensive in terms of money, legacy, and potential further destruction of our sensitive ecosystem.
