The space stations we've built have all been in LEO. The ISS would deorbit in less than two years without periodic boosts. As such, no nearby orbit can be considered stable. The fuel required for boost is proportional to its mass. So it's quite reasonable for space programs to cast of 'dead weight' that doesn't contribute to the mission of the space station.
