I'm missing something here.

Every sampled image takes more space at higher resolution, although compression
can reduce this effect to some degree. In fact, the source file + Ghostscript
can be considered as a compression technique that only adds a constant to
the source file size.

Low resolution images lose details and develop aliasing effects.

Rendering of a PS or PDF file may upsample the embedded raster images and
result in larger output file that the source file.
