They say: "Buy land. They ain't making any more of it."
It's a cute saying, and catchy. But it's bull. The planet is chock-full of land which is practically worthless and will stay so for generations. For all practical purposes it is an unlimited resource. Even in the USA, which is a highly developed country, there are many places you can drive for hours without seing any people or buildings. And that's just in the areas where there are actually roads.
If you want cheap land, go buy it in deep Sebiria or Sahara. Great deals for sure.
No, people don't want land... they want land where there is civilization and other people. It is people which is the resource.
