Why are certain hands like Chicken Hand discouraged or penalized?

The Chicken Hand scores 0 fans. It is a winning hand with no special combinations whatsoever. Because it requires no skill or strategy to build, most rulesets restrict it to discard wins only (you cannot win with a self-draw Chicken Hand) or impose a penalty payment to the other players. The goal of the restriction is to maintain the integrity of the scoring system and ensure that winning hands represent some level of strategic intent.
