I might understand the point if what you were trying to sell was a picture of the tower- that is, if the image of tower itself were the reason people are paying for something.
If it's just part of a crowded the background, though, as in this case, it doesn't make sense. You can't put in the sky an object visible from everywhere and then ask people to pay (or even just ask permission) to use pictures that include it.
