Yep, and time and time again has shown people pay for sooner. I really think people who assume "scarcity" is the only factor in economic models aren't seeing the whole picture. Exclusivity of group membership (I have a t-shirt, jacket, etc. with this awesome logo I can advertise my social status/beliefs), being "first" in a social group, and just plain impatience or apathy contribute greatly. If everyone was purely rational, I'm pretty sure we'll all use refillable water bottles, personal water filters, and buy food in bulk. Assuming the motivations behind every actor in the economy are purely rational is utterly naive.
