But if the law says "this person can only be fired for cause", and the President is supposed to faithfully execute the law, shouldn't he only be able to fire the person for cause? Or what, the President can just choose parts of the laws he doesn't like anymore while operating the executive branch and yet still be found to faithfully be executing the law?

All the laws give limitations on what the executive is allowed to do. So this idea that its limiting the abilities of the executive and that's not allowable seems meaningless to me, that's what the laws are for. The laws are there to define how the executive is to act. The executive is then supposed to faithfully do those actions.

If the President has total control over the executive branch, why can't he just go tell the people in the executive branch to go do illegal things all the time? Is he just no longer bound to the law at all? If Congress says the executive needs to make a food stamp program, should he not be required to actually make one? If the Congress says dumping hazardous waste should be limited, should he not be required to actually regulate dumping? Wouldn't he fail at faithfully executing the laws?
