in SRGB, should read: instead of SRGB.

abject,

I'll have to disagree with you on this one.

sRGB is a certainly a wider color gamut than Adobe RGB (1998), but ProPhoto RGB is wider still. However, either of these color preferences are a really bad choice for print.

All RGB color systems place their gamut within a tilted triangle in a CIE xyY chromaticity chart; the gamut of human vision is a significantly larger tilted "horseshoe" in this same space. But the gamut of what you can print with a CYMK printing process is an irregular but similarly lopsided hextant. Depending on the ink formulations for the specific printing system used, it has gamut within the triangles. The textbook case is printing the color blue; it's uniformly hard to get accurate blue in a CYMK system.

So, the problem with enormous RGB color spaces is that there are thousands of colors (or more) outside a typical CYMK printing gamut. If you look at SWOP or Euroscale CYMK gamuts, you will see on the aforementioned XY chromaticity charts that much of Adobe RGB (1998) is far outside their reach. sRGB however, is nestled well-within. It also has some overlaps and underlaps, but the total displaced areas are far less than for Adobe RGB (1998). This means significantly fewer out-of-gamut problems for print.

A somewhat separate problem is whether most RGB monitors can actually display wide-gamut colors. Color matching wide-gamut RGB for print is virtually impossible. The extra data bits used to compose colors in wide-gamut RGB spaces are essentially useless, if CYMK print is the final target of the image.

The question is what is the best compromise? An narrower space like sRGB has many fewer out-of-gamut problems for print.

A slightly better compromise for specific documents can be to use 6-color or 8-color inking systems, or very specific spot color inks. These alternatives certainly do have wider gamuts than CYMK process inks. In these instances, a wider RGB color gamut may be providential, but in no case does print color have a larger total coverage area in chromaticity space than any wide-gamut RGB color system. There's just no there, there.

To illustrate better, here's a nice color science article on color spaces:
