If someone wants their jacks back due to something they feel is an important enough to remove to make a point. Then, I feel the person should be respected and be allowed to remove the spells.
The importance of that respect is vital. If they feel they were not worthy of the spells, they probably weren't worthy and should be allowed to take them back to make whatever point they wish.
There is another benefit to this action being allowed. It will not be done by but a rare few. So, if that is what makes them feel better about a negative impacted situation, I'd say let them take their jacks back. It's not like we can't get these spells, again. Most spells are not original, anyways.
The importance for giving this control is that even if we don't agree with a person or conflicts arise, if they are so moved to remove their share of a collective pot, then, there is nothing but negative in that pot.
We do not need to control people to the point of toxicity. Let it go. Let them take their jacks back and be done with it. It will prevent further infection of negativity amungst the group.
