The drone killing is a seriously disturbing precedent, but with the backlash that's happened I think you won't be seeing that again (at least I hope).
The rest of your examples are definitely tools at the disposal of the executive branch, but they're on the same order of being put on the no fly list (the no-fly-list was more of an illustrative example than a definitive list of what the government can do). Annoying, but not at all equivalent at all to being jailed (as the parent comment stated).
