The question of whether this dude's property rights do or ought to trump public access to the beach is a detailed point of law, and, I mean, clearly is not as black and white as some posters are making out (neither side trivially prevailed in a summary judgment through the courts). But this subthread is not whether the case was decided correctly on its merits, but whether people who think that Khosla should be able to fence access to the beach through his property are deluded idiots who wrongly imagine that they will someday own beaches themselves, and are agitating for this particular wholly imaginary self-interest, or whether they might have other reasons to believe as they do.
