Before using the App Store, you have to agree to terms of service. No one reads it, but they could! They are told to look at it and must acknowledge they agree before they can use the service. What else are you going to do, force anyone buying any device with services attached to sit in a little room and interrogate them until you're sure they understand every detail?
Do you have Apple Stores in your country? They're almost always packed. Could you imagine how insane it would be to do that? Would you no longer be able buy iPhones online? What you suggest is completely infeasible.
