Having your children abducted and held for ransom. People wanting to kill you because they think you put microchips in their bodies through a vaccine. Not knowing if people you meet are just trying to extract money or publicity from you.
The last "problem" honestly it's more of a compliment , and besides a billionaire's pockets are so deep that the extraction of money via social interactions are small leaks which are not only acceptable but should be again taken as a compliment.
