Even if Trump does not respect the view of the courts, some of those working under him do. They can be held liable if they proceed to violate a court order. If they can be given a legal justification for the orders they are given, it makes it a easier to make them comply with the orders.

But even if those working under him are faultlessly loyal, that doesn't mean the rest of the population is. Trump knows that even his base won't tolerate behaviour that is blatently illegal (such as running for a 3rd term) unless there is some kind of legal justification such as an emergency war situation. This is what I believe this is all in aide of.
