In this setup, would you pay for another car after not getting a return on your first spend? The problem is the incentives. Humans do what they are incentivized to do, largely. What about an $1800-a-night escort that decides she isn't interested in having sex with her customer? She isn't a prostitute, she can choose... but certainly if she exercises that choice she won't have many repeat customers, and if word gets around she won't find many clients at all.
