Right but Al Capone did jail time, here Zuck gets to break and enter into people's homes, take their stuff, then haggle for it after-the-fact, all the while keeping the civilization-domination apparatus that he built using the stuff he stole? That is super not fair. Ordinary people could certainly not get away with that.
The US justice system doesn't start from fair. It starts from what you can prove to the letter of the law.
And when you're targeting someone / something with unlimited lawyers, you'd better have ironclad evidence that exactly that happened in exactly the way the claim is written.
