Some of these pieces of land have hundreds of owners. In this case one of the owners has an interest of less than a one-hundredth of a percent. Most of the owners do not even know what they own. The legal fees to establish who has a fractional interest in the property would outweigh the value of the property normally for each individual owner, but with Zuckerberg footing to bill to find out the family tree all of the owners will benefit.
