The WT's pictures of paradise inevitably show something that simply could not possibly exist without electricity, large manufacturing plants, plastic extrusion, huge logistical & transportation chains, etc.
It's one way to break up the monotony of the meeting - "How many products can you spot that will not be possible with the 18th century style of living that the Society seems to think we'll be living in?"
Heck, even the clothing is all dependent on modern manufacturing. So who's going to smelt the metal, manufacture, and transport all those metal belt buckles all the brothers are wearing? Or are there going to be village blacksmiths with bellows making them all? Who will make the little plastic dingles at the end of the shoelaces of everyone's shoes?
