Welcome to the mordern world
Books, music, images, all created by artists who get paid a little and then lose control as they float about the world on the internet. At least if you are a musician you can get something back from live performances (it works for The Grateful Dead), artists can move to the graffiti world like Banksy, but all authors can do is keep writing new books...
As for the rest of us, there's no much we can do, you can print your own money but that doesn't normally work well.
