It isn't the dirt that makes them safe on the counter, it's the 'bloom' which is a coating that you can't see. Washing removes the bloom. Once they are refrigerated, they must stay refrigerated, because there will be condensation which can wash off some of the bloom. Then any bacteria on the egg can enter thru the shell. Especially with dirty eggs.
99% of my eggs are very clean looking, but they still have the bloom to protect them as I don't wash them until ready to use them. I don't save dirty eggs, I feed them back to the chickens, cooked. I can't imagine selling/buying dirty eggs.
Btw, I refrigerate my eggs, I don't leave them on the counter.
