The point I was making prior about the Golf Memberships is these were places that were exclusive to get into and it is my belief how ever humble that we as owners have a exclusive place to live here and we should not be so quick to give it away.
Once again, fundamentally flawed example. Somewhere like Augusta National is a collective of all it's members. Property owners at the beach are all individuals with different needs and circumstances. For your example to make sense, it would have to be one of two things:
1. All property owners in, say, Sowal, are in an ironclad contractual relationship to keep prices up and or be required to vote and approve any sale.
2. Augusta National would have to allow any member to individually sell their membership anytime they want and for whatever price necessary. Private club, which the beach area is not.
I do agree with one of your points however. If you don't have to sell, don't give it away.
