We don't just "trust" anyone to drive a car properly nor do we trust that people will not shoplift. There are laws in effect that intend to prevent underaged people from driving without consequence (as well as anyone who has demonstrated they can't be trusted to drive properly in the past). And stores often use some sort of system to detect when people walk away with things they did not purchase.

I agree that on a certain level, we operate in a way where we assume people are trustworthy. As far as I know, there are no strict laws on how bank queues work, and there probably don't need to be.

But crowdsourcing? I see it as having plenty of problems, and I can't agree that we just trust people or corporations to accept what is more of an investment under the guise of a donation in a responsible manner. They need to be held accountable for the money they accept.

On the other hand, I feel little sympathy for people who throw their money at projects like this. I wouldn't invest in a flying car if it was just an idea presented to me with no working progress.
