Are you feeling OK there, W4HLN? You seem distressed, and without any arguments to support your assertion.
The President has the power to shut down amateur radio, as in WWII, but he already has that power by law. This new executive order doesn't change that at all. The President can't grant himself powers he doesn't already have, and yes the Constitution and the law still applies in an emergency.
Very true. The President merely need the invocation of the War Powers Act of 1973; 50 U.S.C. 1541-1548.
Reagan, Clinton, and Obama, all disregarded this law for Congressional notification and authorization, stating that they believed such to be unconstitutional. So much for the law.
