Simple? Having to dry it in the oven to drive the water out, then putting it in your safe where it takes up much more room than a Goldenrod? Then, after it absorbs water having to go through the oven drying thing again. How do you figure, Perry?
What could be more simple than a Goldenrod? You plug it in and, for all intents and purposes, forget it.
Not trying to to be argumentative, but why would you want salts in a closed space with your guns when you can accomplish the same thing with low heat?
