You make a couple of really good points - programmers are much better at visualizing how a solution would work than the general public. Also, sometimes people really, really just don't know what they actually want :-) However on the flip side if people can't understand what I am proposing or why they would want it, it means I am going to have a much harder time selling it to them. Suddenly my task is not about coding and marketing but more about first building the market, so I can then sell to it. Its probably a good opportunity for somebody, but I'm not sure that person is me :-)
