I think it takes incredible courage and discipline to grow up in a posh, upper-crust, aristocratic, monarchical family and literally come out against them. He wanted to be in a combat position instead of in the Navy playing on boats like his dad; he bucked the trend, went against the family, and when he wasn't supported, he put his middle finger up and said, "Fuck you, I quit."
That's hard as shit, literally difficult, and the street meaning.
Sure, he had everything, he still does. He ain't going hungry.
Think about if this is a Rockefeller or Rothschild airing family laundry like this. The motherfucker would be killed.
