I can see were you're coming from to an extent but on the other hand if the default stone wall texture suits the wall I'm building why should I waste time creating something different? Does it make my piece of art any less worthy? There are plenty of images that seem to fit the poser + someones sword model type of thing here but IMHO that's just part of the place.
