One can allow for indirect economic circulation, such as you buy from A who buys from B who buys from C who buys from you, but an ironclad rule is that giving out more gold than you get will eventually leave you un-rich. Especially if you are immortal, like a country.
Countries become "un-rich" by running budget deficits, not trade deficits. My country does not pay my rent, or buy my beer.
I purchase less than I earn. I'm not getting un-rich. I could repeat it a few more times if that will make it clearer for you.
