Because there is no built-in action for converting RGB to CMYK. And there is good reason why there is not. Even more true today than 12 years ago, to correctly convert RGB to CMYK, you want to convert using the CMYK profile that represents the exact printing conditions, as well as properly setting the other options correctly such as Rendering In the Photoshop (Edit in Windows) menu > Drag down to Color Settings >.
