Why do professional print houses use gamut-limiting CMYK?



I recently had some business cards printed, and was warned to use the CMYK colour space if providing TIF files. When I tried saving from Paint Shop Pro to a CMYK, of course the colours came out very much duller, so I provided a different file type that preserved my colours using RGB. To my horror, the cards came back nevertheless converted to the CMYK dull shades.


A few months previously I had been in a hurry and had printed my own one-sided quasi business cards using glossy photo paper and a cheap home printer. This reproduced my desired colours perfectly.


Since the whole point of using professional printers is quality (though I admit bulk as well), why do they not use printers that can cope with the RGB colour range? FYI: the main colour in question, which I chose very carefully, is a slightly yellow-tinged lawn green, which I understand doesn't feature in the CMYK gamut. So why use that gamut, and is there anything I can do to overcome this issue and get cards printed in the colour I have chosen?
