The East Germans also had a law aginst "desecration" of the flag of the DDR. And only a "psychosociopath" would claim to own a copyright on the US flag and personally own every US flag in America. You have much more in common with them than you might want to admit.
Probably long past time for you to check and see if your visa is still valid, whdda'ya say, eh?!
Never mind that under US law, copyrights expire and enter the public domain eventually. Which under a strict definition would mean that no one could "own" it upon expiration...
