Yes, even when people copy eachother they don’t have the same output. And some individuals are mighty excentric, for instance Picasso. But most people stick almost entirely to what they see and only differentiate by means of the mistakes they make, not by intended originality. From the moment people are born they start copying everything they see. With a head full of mirror neurons we tend to live our lifes exactly the same, and the difference only stand out because of they’re relative. From a distance we would all look, behave, be more or less the same. Copyright should be abolished. Support whoever you will out of free will, but don’t limit others freedoms to copy you. The idea that what you make can’t be copied is an immoral absurdity.
