Players are powerless from someone stealing a gatherable node

If I am gathering a node (tree, plant, ore, etc.) and someone comes behind me, flags up, uses a CC skill, and then steals the node while I'm incapacitated, there is literally nothing I can do to prevent this from happening. Since they are not damaging me (and especially not killing me) there are no negative effects on their end.

Except for retaliation against the provoking guild, what suggested mechanism in the game could mitigate this?
