Since people tend to want more, and since we're all subject to boundary conditions posed by nature, compromises need to be made in certain cases. A good example is the driving situations in Japan/China where if you have an even numbered license plate you can only drive on certain days.
Also, central planning != micro management. Just general guidelines similar to things like building codes. But really, not sure how it would really work.
