The reasons for the harsh penalties in these two rules are plain and simple to me:

1. Being under defense while hanging increases incidental contact while hanging
2. Incidental contact while hanging 3 feet in the air increases the risk of damaging one or more robots
3. Let's face it, some teams will literally try to pull another robot down off the tower, regardless of intent of any "defense is allowed" rule
4. Damaging one or more robots ruins many individuals' day
5. Damaging one or more robot while in contact with the tower may also damage the tower, ruining everyone's day due to the delay caused by repairing the tower
