Maybe so.
But as a show of hands, how many players here are comfortable with a DM that privileges a process of play that allows him to deny you fortune tests when he wants to mess with your character?
One thing that in my experience players don't like is a feeling that they were being treated unfairly. How many players have you had who would be ok in the long term with ideas like, "You don't even get a resisted check to oppose the pickpocket because you didn't say the magic words I wanted to hear?" I can't think of any.
That's a pretty uncharitable way to present that.
