If you encounter unused land or resources that have no geneaology of ownership, then you are entitled to claim as much of it as you are prepared to immediately and actively use. Once you have done so, it is yours to use, buy, or sell; however, you cannot "horde" property under initial use. I.e., you cannot stop exploiting the aquizition and exploit new aquizitions for the sake of seizure. You must actively, and consistently be using all initial use acquizitions in order to rightfully claim additional acquizitions under initial use.
