You’re missing the point. Nothing is being forced upon the player, the player is not being controlled.
The whole purpose of it is to allow the player to be free and play as he/she wants. BUT in the ocasion that the designers believe that a certain playstyle or a certain action makes the game experience more enjoyable, rewarding a player for playing the game in such way is a good way to encourage the player to do so.
This way you’re not taking the freedom from the player to decide by him/herself how he/she thinks is the most enjoyable way to experience your game
