They are not lies. He does not expect you to believe them. They are power-play.
He does not tell the untruth because he wants you convince you of something. Telling something that is obviously not true is a gesture of dominance:
He is demonstrating that he is dominant over you by demonstrating that you are beholden to basic rules but he is not.
Trump's "lies" are a deliberate demolition of norms to show his dominance over society, its rules, and you.
By telling his "lies", Trump is rubbing it in your face that he is getting away with it: grabbing pussy, hypothetically shooting someone in the middle of the street and declaring as true what obviously is not true.
Except that is not real power. It's a show of power. Like a peacock flashing his feathers or a lion or baboon showing off his teeth.
It's gesture meant to impress and intimidate you. It does not mean that he actually is as powerful as he pretends to be. Any scrawny old lice-infested lion can show off his teeth. And you are a giraffe.
But you know what a giraffe can do to a lion?
