I'm from Sweden, and our rules seem quite a bit less permissive than California's.

You're allowed to move freely on most land, and even camp there. But that right ends when you're within sight of the owners home.

California law has no such exceptions. You're allowed on the beach up to the high tide level, regardless of if somebody's home is right there.

Which any soon to be property owner would know before buying a place. If the rules were a surprise to Mr Khosla he should be suing his realtor and not the state.

Well, as a fellow swede I can say that this is only half the story, because not only do we have the very extensive right to roam law, but we also have an additional law regarding this in particular called "Strandskydd" (literally beach protection) which makes it very hard and exceptional to make a coast line private.

Seems like a loophole where anyone would build a house close to the water to prevent public access.

France too IIRC.

Hawaii too.
