I guess it depends on your attitude. I don't see that as a work around.
As for why the top view is as it is, it starts with the standard front view which is the view you get with the default solid red axis running to the right and the solid green running away from the camera. The other standard views including the top view are correctly developed from that view. These are standards that have existed since before SketchUp. Look at any textbook on drafting.
The default axes are located such that the red(X, solid red = positive) and green(Y, solid green = positive) are on the ground plane and solid blue is positive Z. Moving the axes does not change the real X,Y,Z orientation or the orientation of the standard views. It doesn't change the location of the ground plane, either.
In over 10 years I haven't ever found a need to move the model axes but I've seen plenty of cases in which moving them has caused other people grief.
