The photographer tool is like the Lawer's suit or the Real state's car. If they look expensive it is a sign to others that they have money. And if they have money it means to people they are successful (and therefore good) on what they do. Even if not true, people will take advantage of others perception to feel more confident about themselves.
Also, the expensive tool makes the owner enviable (as the example of success), the others envie is the biggest self reassurance.
I think people feel more confident when they work with gear that make others perceive them as serious or even professional, gaining their respect and credit. It doesn't mean more expensive gear though. But if it looks expensive people tend to give more respect or consider him a more serious photographer.
