I'm going to posit a simple reason for his disdain towards the rule of law having nothing to do with the way he eschews an intellectually curious approach to anything. That isn't related to his obvious ignorance of, and lack of interest in, America's founding.
Namely, he has sought to skirt the law his entire life. He sees it as an obstacle in the way of following his natural impulses. Which are to take advantage of situations that will benefit him in some way. Even if it means breaking the law.
He got his feet wet breaking anti-discrimination laws at his dad's rental property and lying about having bone spurs to avoid the draft. He went on to defraud investors in his casino company, cheated contractors, laundered money for Russian oligarchs, defrauded students at his phony real estate school, committed hundreds of acts of business fraud over decades while running the trump Org., stole money from a charity, committed adultery countless times (immoral, not illegal), paid for the silence of a porn actress to influence the outcome of a presidential election, extorted Zelensky, plotted to steal the 2020 election which he had lost, violated a subpoena to return stole classified docs, and broken too many laws during trump 2.0 than I can count. Illegal/immoral acts have been the consistent through line of his whole life.
