But you can't pay 5c to read just an article in the physical newspaper either. You'd pay $2 for the entire newspaper if there's an article there that you really want to read. Likewise you don't get a 5c discount in McDonalds for removing the pickle.
And now Google today has launched "Offerwall", which lets publishers accept payments of 50 cents for one-day access to their websites. Exactly like buying a physical newspaper.
