The right to distribute a thing at scale and the right to buy a single copy for yourself just can't be the same thing. Should a movie theater that sells ten thousand tickets have to pay the film studio for the cost of a single DVD and then be free to do whatever they want?
And yet that's exactly what you're "buying" when you crowdfund a freely redistributable work. Even some movies have been crowdfunded in this way, such as the animation movie Big Buck Bunny.
