Wrong. A game must be balanced around what is possible and not around the expectations that the player will not use certain options available to him.
When pickpocketing is possible it means the game must still work when the player pickpockets everything instead of becoming completely unbalanced, even if that means some entitled players whine that they can't have easy mode (besides setting the game to easy).
If the game requires you to pickpocket repeatedly to be successful or complete the game then I understand your frustration. But if it doesn’t make a major impact then I don’t see the balancing issue.
