All the money and fame in the world doesn't do much protecting at all: it can lock you in the depths of your mind. Imagine a situation where every interaction you have with other people is fawning or fraudulent. Where all day, every day, someone is either kissing your ass or wiping your ass. Nothing is genuine. Nothing can be trusted. Everyone wants to use you to their own ends.
Fame and the life it brings seems desirable, but there's ample evidence that would indicate otherwise.
If you think about it, it's no wonder so many famous people are depressed, dysfunctional, or disgusting - their self worth and ability to self-evaluate are completely distorted. And the pressure of maintaining that fame, that score that many believe determines how important you are to society, is crushing.
If you're not happy, not content, not satisfied with yourself when you're a "nobody", becoming a "somebody" won't change that. Whatever issues you brought to the table before you got fame and power won't be improved once fame and/or power is acquired. The Good Book says something along those lines a few thousand years ago:
"Whoever can be trusted with very little can also be trusted with much, and whoever is dishonest with very little will also be dishonest with much. - Luke 16:10
