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.

A problem of Adobe RGB is that it is smaller than the color space of most images captured by digital camera sensors. ProPhoto RGB is large enough to contain these colors, a lot of which are deep saturated colors. Why throw away information? I understand that ProPhoto is larger than what we can see. I also understand that ProPhoto is larger than any output device that we have today (print as well as monitor), but who knows what the future holds. Some of the colors that fall outside of aRGB fall within the colors of modern inkjet printers.
I agree, problems can occur when adjusting the color in ProPhoto. But, if a person understands color management, soft proofing and how to turn on the "out of gamut" warning, then ProPhoto will pose no problems. A person has to understand. That is all. If a person does not understand all of this, then aRGB is a safer space to work in. But, if a person wishes to maybe one day take advantage of all of the colors that their digital camera sensor can capture, then ProPhoto is the answer.
