That's totally different - indictments are usually sealed before arrests in the kind of case you're talking about and there is longstanding precedent for that to prevent flight from prosecution. They would arrest you for ITAR and IEEPA violations before you board. That kind of thing happened long before the no fly list. That is different than an opaque list with a million people on it most of which have never been accused of anything and where there is an expensive appeals process and the government is allowed to use secret evidence.
