Would your friend have enjoyed themselves that much if they were a women? I think not. Would your friend enjoy themselves in every dictatorship in the world? Probably not. You can ask him if he has to be sent to a random Western democracy or a random dictatorship, which one would he bet on. Which one would you bet on if that is the choice?
When the power is concentrated in the hands of one person, all of it is up for abuse at all times. When power is something that is spread to more people, diluted through a more complex system and processes, less of it is actually up for abuse.
If a monarch wants to ban a religion, the religion is banned. If the US president wants to ban a religion, he gets taken to court.
To put it in your terms, if you get fucked by one person, you get fucked whenever that person wants to fuck you and you get the whole dick every time. If you need to get fucked by a committee, most of the time they would be bickering about who gets to do what, what part of the dick belongs to who and all you get is part of the dick from time to time or somebody sneaking a pinky while the others are not looking. Checks and balances is not that dumb of a concept when your ass is about to be violated.
