Well, the benefit is that you get a photographic texture that perfectly matches the mesh...which can be reduced without any problems. IT would take a little time, but building something from scratch would take more time.

300 photos of a building (or museum exhibit) could be taken in half an hour to an hour, producing a very high fidelity mesh, without any additional effort.
You couldn't achieve that in such a short time using traditional modelling methods.

And again, it won't be messy if you carefully photograph the subject in reasonable lighting. Look at the videos.
