Air travel has been considered luxury until recently and may still be for most. China has a very developed passenger train network and road network. The train ban for non-safety-related cases only bans travelling in first class/sleeper cars and G trains (high speed trains). You can still travel in regular train cars. So the spirit is more like: if you refuse to pay or claim you can't afford to pay, you shouldn't be able to travel with too much comfort.
