Because the color space in your camera is much larger than the Adobe RGB color space <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/biggrin.gif' class='bbc_emoticon' alt='

I know it is, but converting from one colour space to another is/can be problematic. It makes little sense to work with a big or huge color space if the intended output does not support that. Also, using a big color space that your screen can not even handle makes little sense too.
One of the problems of ProPhoto RGB is that it exceeds the visible spectrum in some areas of deep blues and deep greens. When editing an image it can happen that you shift colours into these fictional ranges, which can not be seen or reproduced, which can cause problems in the colours we see.
Also, since the gamut spaces are so wide, and does not have such wide gamut, the screen is not always capable of showing the effects of changes you make, especially with hue or saturation shifts.
ProPhoto RGB only really makes sense theoretically. Especially for people who have not too much understanding of what it means to work in 16bit colour spaces, color management fundamentals, soft proofing. Adobe-RGB is a safer option, if you feel sRGB is not wide enough.
