The article is basically saying that "nature" should be more important than GDP. Perhaps that should be. National treasuries are linked to GDP because most taxes are either a consumption or an income tax, both of which are tied to GDP (consumption is paid by a buyer, income tax by a seller, either way, they are parts of GDP). Most arguments that try to say, GDP is unimportant or shouldn't be important are advocating for something that would ultimately shrink GDP, and reduce government incomes. Usually while making no case for anything other than, "making due" or austerity. This usually creates an unsustainable political climate leading to eventual regime change to something that will create economic growth.
