Can you restate your question? The economist qua economist doesn’t “run a country.”
If you’re asking how does an Austrian economist explain an economy rich in natural resources, the particulars and amounts of resources aren’t relevant for economic analysis. Austrian economics uses a deductive method starting with the premise of human action. The particular ends and means (resources falling under the category of means) aren’t what is relevant, but rather the structure of human action, the fact that human beings do have ends and means, and the conclusions we can deduce from that.
