The problem is that the things he’s doing are using his office to become an actual billionaire and tearing down protections against abuse and fraud. You don’t fight “institutional rot” by enshrining the principle that loyalty trumps following the law or that policy outcomes can be purchased on the blockchain. Lying about the law and actions by his predecessors similar is building, not lowering, institutional rot by encouraging the idea that cheating is okay as long as you win (c.f. continued lying about election integrity or awarding government funds and jobs based on political affiliation).
