Generally, people are not "fundamentally good". Generally, most people are only good when they believe the reward for being so is >= the required effort or discomfort (rewards aren't always monetary and could be as simple as feeling good about yourself for helping the crippled-orphaned-widow-beggar across the street). An example of this is airbnb's own policy of not disclosing renter contact information. Despite what they say, airbnb believes that people are not fundamentally good as their concern of users circumventing their payment system is greater than their concern for the safety of said users (at least to the extent that stories such as this don't hurt their business more than payment bypassing would). If airbnb believed what they espouse, they'd quit trying to outsource their trust in humanity to their customers whom they aren't liable for and instead actually trust that people in general won't sidestep the payment process.
