@futurebird I think President Trump and his handlers all do this political calculus in their heads as to what benefits them personally and they conclude it is best to selectively obey the law even when they don't like the outcome, like it is medicine that tastes bad or has side effects but ultimately makes you better overall.
To ignore ALL law would quickly incite rebellion against him. To obey all law is intolerably limiting to him, so the sociopath tries to calculate where the boundaries are that serve him best.
In this regard the battle over the name of a building is an easy decision. It isn't really important beyond ego stroking so if you just put up a bit of a fight on court then ultimately comply with orders he now has a new grievance to bitch about to his deluded admirers. "It's lawfare! This is why we have to Fix the Courts!"
So the calculus works in his favour. Grievances to defend the ultimate goal are worth the cost of hurt feelings.
