I don't think texturing is necessarily more "right-brained." Rather, it's more detail-oriented. The part of the brain that accountants and copy editors use. Modelling is more spatial - the part of the brain the engineers and airplane pilots use. (While modeling can be very detailed, it doesn't have to be.) Both are equally creative. In fact, the argument could be made that modelling is more creative, because you have to make something new. Texturing is just modifying something that already exists.

Texturing is less intimidating for many people, but IME, isn't not necessarily easier. Sure, anyone can make a texture. But making one that looks decent is a whole nother story. I do on occasion make my own textures, but they look awful. If I tried to paint my own belt, the edges would end up looking jagged, the seams probably wouldn't match up properly, and buckle would look pathetically fake.

It's not easy to model conforming clothing, but that's due to the difficulties of the conforming process. Modelling non-clothing items is pretty easy, IME - more so than texturing. I have very rarely been able to make a texture for an item that I'm willing to show in public. But I use models I've made myself in many of my images, and on occasion distributed them as free stuff. (Textures usually courtesy of nodes in the material room, though!)
