Down here in Los Angeles we have many rich homeowners who use fences, fake/unlawful signs to keep the public out of local beaches. Many of these beaches are in Malibu he seem to think they are above the law. There are now mobile apps that tell you where these secret beaches are and how to access them (some access routes are very hidden).
The shenanigans that Malibu residents do to keep outsiders away is astounding. David Geffen has his entire street side of his Malibu house covered in fake garage doors with corresponding curb cuts so you can't park there. (Technically you are allowed to park there, but try explaining that "these are fake doors and illegal curb cuts" to parking enforcement)
If I remember correctly, I believe there was a recent article stating that there was a new raise in fines for them pulling these shenanigans. I suppose most are still too rich to care, but if you had enough people calling them out consistently, I suppose it could make a difference.
Not only do the residents of Malibu do an amazing job of keeping the general public off their public-access beaches, they also seem to have a knack for crafting ordinances and environmental regulations that keep outsiders from moving in.
In 2000, Malibu had a population of 12,575. By 2010, the population had grown by a mere 0.55% to 12,645. Compare that to the entire state of California, which during the same period grew over 10% and added 3.5 million residents.
