Getting rid of your king is a big deal. But simply inventing a new king, the U.S. government, not so much.
They called it "self-government", but it was just more of the same, with new actors. Taxes were now higher, and the President of the USA possesses powers George III could only wish he had. Now Americans have "3,000" tyrants nearby, vs. 1 tyrant 3,000 miles away.
