Why No Rotating Space Stations?

To produce artificial gravity, all you have to do is spin your space station at the correct speed.


Why are there no space stations that spin?


Sci-fi movies have been ahead of real technology on this simple point.


We know that extended weightlessness significantly decreases bone density and muscle mass, even with vigorous exercise. Creating artificial gravity by spinning would be a simple solution. Why hasn't it been done yet?


The cost of assembling a complete wheel as in "2001: A Space Odyssey" would be incredibly expensive, as this video explains. The movie "Stowaway" presents a much less expensive design (shown below) with three parts of the spacecraft spread out by cable and then set in a spinning motion.
