Gunnar_Zarncke comments on Alex Tabarrok advocates for crowdfunding systems with *Refund Bonuses*. I think this might be a natural occurrence of a money pump against Causal Decision Theory pledgers

Seems like a case where civilization should offer something to improve overall coordination—not the project itself which can’t (where is the money for the bonus supposed to come from?).

Or maybe have a prediction market of these projects. Maybe let the project itself subsidize it—could be cheaper than a bonus.
