No, here you are wrong. It simply happens that CSG is harder to do if you
don't use plain ray-tracing. And the default renderers shipped with any
commercial package today do not use plain ray-tracing, but various hybrid
scanline/ray-tracing methods. And those methods cannot easily do CSG, but
they need to precompute what they call CSG in the modeler interfaces...
