In the current scheme, if Kickstarter released the funding, to then realize within days that the campaign was fraudulent in critical ways and/or the system was compromised to get the funds to a unrelated entity, they'd revert the transation at the processor level and make whole everyone involved in a relatively light process. The options to game the system at scale are limited (by design), and that builds trust in the processors. The automatic trigger baked into the system that you describe feels to me way easier to game, with rollbacks so expensive to do that it wouldn't happen short of something catastrophic directly affecting the very powerful entities. So not just for an eggregious scam affecting a few thousand users...
