That is one of the typical design features of a game like this. Though it may seem foolish to you, it does fit with the model. Keep in mind that some aspect of the game do need to be linked to monetization (AKA making money), since we developer also like to eat food and pay our electric bill :)
in fact... have user created levels... the free mode at the end is nice, but with a little more code it will be a complete level editor. and then sharing user content will be possible!
