Owning land is important because it is a source of wealth. Land can be harvested and the materials grown on it sold for profit. Factories, warehouses, and buildings can be built on land that will facilitate business. Land can be leased in return for income. Land is also a tangible good that does not depreciate. In addition, land cannot easily be tampered with, in that there is nothing to steal from it. It can be polluted, but that can also be prevented to a degree.
