In no way do I favor the driving of nails into trees- totally opposed. The point you are missing is that the nails are already in the tree. To remove them is far more damaging to the tree than for them to remain- removal a decision in favor of an aesthetic concern rather than a decision favoring the well-being of the tree. Since they are preexistent one can certainly move with grace and concentration in order to hang a water bag.

Sorry, I didn't mean to sound as though I was accusing you of anything.  Only making a point that is dear to me.
