The thing I don't understand is why police don't simply cut the lock every time Khosla locks the damned thing. It's gone to court, he lost (as he should have), and now he continues to blatantly violate the law. Petty criminals have been shot and killed (thousands of times) over less blatant disregard of a legal order, but a rich guy can get away with a massive theft of a public resource for years without any consequences. Money may not buy happiness, but it certainly buys the right to be a truly awful human being without consequence.
Why can't a citizen simply call the police every time a gate is closed and locked? Send Khosla the bill for a locksmith or whatever it takes to restore access. Cities do it for overgrown lawns (which is harmless, IMHO), and this is causing actual harm to the public good.
