[Harry Potter and the Goblet of Fire] Why must Harry compete in the Triwizard tournament at all? Even though his name came out of the Goblet, no one is putting a gun to his head forcing him to do these challenges. Why go through with the events at all?

Actually they did have a sort of magical gun to his head. In the books, it’s stated that the students whose names come out of the Goblet are magically bound to compete. That’s why it was a big responsibility to enter. If you were chosen, you were bound to see it through. That was how (fake) Moody ensures that he would be in the competition, because he was the only one submitted for a fourth school, and everyone whose name was selected would be bound to compete.
