Also, proper color separation (ie, the kit comes molded in all the right colors) is a rather modern phenomenon. Kits used to require FULL paintjobs back in the day. And even now, color separation isn't perfect--often due to budget or complexity, you'll still get parts molded in the wrong color. So painting is needed to fix those areas.
