In the meantime, I would really appreciate a summary of why "it's legal therefore it's okay" is not a good answer. The Ottomans deliberately enacted liberal property laws to increase immigration, and thus tax collection, from the area. It was literally the stated goal of the government at the time.

One answer to this point in particular is that this wholesale liquidation of the land was made by rich landowners living far away, and cannot be treated as the Palestinians selling their own land away. The people actually living on the land had no say in this.
