Hell no. Crowdfunding is not guaranteed. You think every KS backer is satisfied? There are tons of projects that are never completed and no one gets a dime back because of KS terms. Crowdfunding is not purchasing a product, it is investing in a company in the hopes that they make something. That is why they are called pledges and not purchases.
Besides, this has already unsuccessfully been done in pinball...see Predator or JPop
