Those out to harvest souls to power projects contrary to the will of God probably don't want many to know the truth which would reveal their own value among other things. Cradle-to-grave indoctrination of "everything that has value is external" is "big business" (i.e. sex, drugs, shiny things, etc.). It has even been indicated that most energy in the Universe comes from living organisms rather than from clinical, sterile, soulless physical processes.
P.S. David Merrill's point is probably to express affinity with the Inner Kingdom.
