Registering allows you to sue for more money than if you don't register, Maximum is $250,000 per infringement if it is registered (and possible jail time for 10 or more infringements). If it is not registered then liabilty is just (simplified version) the retail price of each work infringed. So, without registering it and without ever pricing it for sale, it could be argued that the damages would be $0.
