Weasel words, anyone? What is the distinction? Is that like saying the papacy or ecclesiatical hierarchy of the RCC don't exist because they are a mere "theological arrangement?"
The way I look at that statment is that JW Spiritual Food is a bona fide product, like Kellogs Frosted Flakes. The cereal has a spokesperson of a talking tiger named Tony. He thinks that Frosted Flakes are Grrrrreatttt! It would be like if someone choked on a too many flakes and tried to sue Tony the Tiger for their damages. The appropriate response would be, "You can't sue him because he's not real." And if the cereal company was strategically broken up into a web of corporations the common person who eats the product regularly would not be able to touch them legally and therefore might be forced to sue a legal construct.
