The issue here is that many of the comments have devolved into "gratuitous negativity."
This is a problem between you and my brother, not you and me. This is also a story as old as colonialism.
If you think this is all fine and dandy, and lives up to the greatest virtue of capitalism, please replace the horse in the analogy with shareholders having partial ownership of a company, and being forced to give up their stake, just because Zuckerburg paid off the biggest shareholder.
Nobody's putting a gun to his head, forcing him to buy 700 acres of land in Hawaii. If he can't come to an agreement with all the owners of the land, he should go back to California, instead of suing minority owners. That's generally how business works.
Large-scale reverse splits occasionally happen in real life, as a means of forcing smaller investors off the ownership rolls.
Again, RTFA.
He isn't conducting the lawsuit out of some strange desire to figure out who is related to whom, or to clarify some papers. The purpose of a quiet title lawsuit is to steal a piece of land from its owners.
Discovering who the other claimants are is the first step in this process. The second step in this process is... To force them to put their land up for auction, where it will be sold to the highest bidder. The current landowners have no say in this. [1]
And, at the end of the process, Zuckerburg's investigation and attourney fees will be billed to... The owners of the land. For some of those parcels, they are quite likely to be higher then the cost of the parcels.
You couldn't come up with a less fair law if you tried - because it was specifically designed to benefit a wealthy party, that wants to take possession of a bunch of land, and the only thing in the way is a bunch of peasants who refuse to sell.
