While I agree with some of the logic in here, it already works if you are on the inside of being recognized and successful. If you aren't known to anyone yet, and someone plagiarizes your work and they get all the glory for it and a lot of stuff is inspired from that work, that person that stole your idea benefits and everyone that was inspired to copy off of that stolen work benefits, but you, the one that did all the original hard work is left with nothing but a pocket full of lint.

Take me for example. If my photography gets stolen and becomes famous around the world under someone else's name he gets all the money for it and then by the time I am able to fight to reclaim my copyright ownership back on my property, he has become a well known name and I am still no one in the grand scheme of things. Or with the movie script I am finishing. If it were to be leaked out and someone claims ownership of it and the movie is made, they get all the credit for my work and I have to work on writing a new movie. All the while new movies will be inspired by my original work.
