The Frunk needs to be viewed as an Engineering Masterpiece..........replacing something unsustainable and unnecessary that has been created and protected only for profit with the "Nothing". Nothing but usable and beneficial space. To me the Frunk is a metaphorical representation of the 11th chapter of the Tao Te Ching:
"Thirty spokes share the wheel's hub;
It is the center hole that makes it useful.
Shape clay into a vessel;
It is the space within that makes it useful.
Cut doors and windows for a room;
It is the holes which make it useful.
Therefore profit comes from what is there;
Usefulness from what is not there."
