You're in the middle of the desert so I won't pretend to say I know what you mean, never driven there so I'll take your word for it. That being said, people have used the same excuse up here, in New England also. We get a fair amount of rain and the roads will get a little slick when the rain first starts but nothing that even remotely calls for 4wd.
The problem is, many people spin their tires a bit, put it in 4wd, they can now accelerate better so they drive faster. The problem is, your braking is reduced by the same amount due to low traction whether you're in 4wd or 2wd. If roads get slick and you put it in 4wd AND slow down, great, but most people tend to drive faster because they think they have sooo much better traction in 4wd.
Still don't think it's necessary in the rain though
