While sometimes user actually knowingly make those trade-offs, I suspect many think they do a quite different trade-off. It's not really that people trust you that much, it is more that they in the moment you ask don't understand the consequences at all. Unless you very explicitly tell the users about the risks, that they wold have zero recourse if something goes wrong, they will believe it is okay for them, that somehow everything is taken care of. Very similar to the why people fall for con men. Nobody expects someone to have the audacity to lie so grandly, act so confidently, while in truth being completely 'naked'. You tend to assume that the insanity must have a point, that the obvious loopholes must somehow be covered - taken care of - based on nothing but the fact that someone acted with confidence.
