The model for such practices is the Perky Pat layouts in Philip K Dick’s Three Stigmata of Palmer Eldritch. Homesick offworld colonists are able to project themselves into Ken and Barbie-like dolls who inhabit a mock-up of the earthly environment. But in order to occupy this set they need a drug. In effect, all the drug does is restore in the adult what comes easily to a child: the ability not to believe, but to act in spite of the lack of belief.

In a sense, though, to say this is already going too far. It implies that adults really have given up a narcissistic fantasy and adjusted to the harsh banality of the disenchanted-empirical. In fact, all they have done is substituted one fantasy for another. The point is that to be an adult in consumer capitalism IS to occupy the Perky Pat world of drably bright soap opera domesticity. What is eliminated in the mediocre melodrama we are invited to call adult reality is not fantasy, but the uncanny - the sense that all is not as it seems, that the kitchen-sink everyday is a front for the machinations of parasites and alien forces which either possess, control or have designs upon us. In other words, the suppressed wisdom of uncanny fiction is that it is THIS world, the world of liberal-capitalist commonsense, that is a stage set with wobbly walls.[...]

fantasy's pathetically imbecilic manichean oppositions between Good and Evil, Us and (a foreign, contagious) Them are effective on the largest possible geopolitical stage.
